As you are aware, websites and software are frequently updated. When you follow these instructions, you may see some differences between the actual installation process and the process described in the instructions.

Unless otherwise stated, Windows, Java, Eclipse, and Cygwin components are assumed to be bit. Look in Appendix 15 – Using bit Software if you are interested in bit versions.

Eclipse requires Java Platform, Standard Edition (Java SE) to run. The main text of this document describes how to install Java SE 11, specifically Oracle OpenJDK If you need to install a different Java version or variant, look in Appendix 8 – Installing Oracle JDK for Java SE 11 (Long Term Support) and Appendix 9 – Installing Legacy Versions of Java SE.

Eclipse, Java, and Cygwin components

To use Eclipse for Java and/or C/C++ development, you shall install all or some of the following software components

• Java Development Kit (JDK) for Java Platform, Standard Edition 11 (Java SE 11), one of the following

  • Oracle OpenJDK – free, open source license

  • Oracle JDK – if commercial license is required

• Eclipse, one of the following

  • Eclipse IDE for Java Developers

  • Eclipse IDE for Java EE Developers (includes IDE for Java Developers)

  • Eclipse IDE for C/C++ Developers (includes CDT below)

• Eclipse C/C++ Development Tooling (CDT) if both Java and C/C++ programs are to be developed.

• Cygwin (Devel package) if C/C++ programs are to be developed.

Enabling Programming Languages

Enabling all programming languages

To enable everything - Java, Java (Jakarta) Enterprise, and C/C++ development - install the following combination

• Java SE Development Kit (JDK)

• Eclipse IDE for Java EE Developers (includes IDE for Java Developers)

• Eclipse C/C++ Development Tooling (CDT)

• Cygwin (Devel package)

Total disk space that is required to install all mentioned above software is approximately 11 GiB.

Enabling Java SE programming language only

To enable only Java SE - install the following combination

• Java SE Development Kit (JDK)

• Eclipse IDE for Java Developers

Total disk space that is required to install all mentioned above software is approximately GiB.

Enabling C/C++ programming languages only

To enable C/C++ development only - install the following combination

• Java SE Development Kit (JDK)

• Eclipse IDE for C/C++ Developers (includes CDT below)

• Cygwin (Devel package)

Total disk space that is required to install all mentioned above software is approximately 11 GiB.

Specific programming languages requirements

You may save your time and disk space if you install only necessary software components.

Here is a table that describes minimum software requirements depending on programming languages that are used for development. Select the column corresponding to the languages and install all components marked with Yes.

The temporary setup space mentioned above includes disk space needed to store setup files (the downloaded ZIP archives, packages, and setup programs). Unless you remove the setup files after each step, you will need disk space equal to the sum of the installation and temporary space.

Note 1 - C/C++ Development Tooling (CDT) is an add-on to Eclipse. If a mixed C/C++ and Java development is required, install Eclipse IDE for Java (or Java EE) first and CDT add-on second.

Note 2 - To run Java Enterprise programs an appropriate Java Enterprise Application Server is required (that is out of this document scope).

Introduction

Java Platform, Standard Edition (Java SE)^🌐 is a software platform that lets you develop and deploy Java applications. Eclipse IDE is written mostly in Java, for this reason, it requires Java SE to run.

If you are developing Java programs, you will also need Java SE to be installed. In many cases, the same Java SE installation can be used to run Eclipse IDE itself and to develop and run Java programs via Eclipse IDE. It is also possible to install multiple versions and variants of Java SE and to use some of them to run Eclipse and some of them for development.

Requirements

It is recommended to install Java SE 11 bit Development Kit (JDK). Free (open source) JDK variant is called Oracle OpenJDK, its installation is described below. If you prefer a commercial variant, see Appendix 8 – Installing Oracle JDK for Java SE 11 (Long Term Support).

You will need approximately the following free disk space before installing Java SE 11

Abovementioned temporary disk space is required to store downloaded OpenJDK ZIP archive file or JDK setup program file. You can remove these files after completing the installation.

Using Legacy Versions of Java

You may install Java SE 10 or Java SE 8 instead of Java SE 11 if so needed. When running legacy Java SE setup program, the setup screens are very similar to the example screenshots below, the main difference is the Java banner color.

See Java Standard Edition 10 (bit) and Java Standard Edition 8 (bit and bit) in Appendix 9 – Installing Legacy Versions of Java SE for more details.

Note - Java SE 8 does not have public updates after January Java SE 9 has reached end of support. Users of Java SE 8 and 9 should switch to Java SE 11 or

Downloading Oracle OpenJDK

To download Oracle OpenJDK for Java Standard Edition 11, in your browser, go to JDK 11 General-Availability Release^🌐 webpage.

In the Builds section find Windows/x64 line and click on zip^🌐 link.

Depending on your browser, you will get a download prompt. Download and save the ZIP file. See Appendix 11 – Downloading and Running files from the Internet if you need help with it.

Open the folder containing the saved file. For example

OpenJDK Parent Installation Folder

Decide where you want OpenJDK to be installed to (the installation folder). You have two choices

1. If you are going to use OpenJDK and nobody else – install it in your data directory, for example, under C:\Users\Richard\OpenJDK. You will not need an administrator access to install OpenJDK in this case.

2. If other users are going to use Eclipse – install it in the program directory, for example, under C:\Program Files\OpenJDK. You will need an administrator access to install OpenJDK in this case.

The table below describes the parent folder selection. Substitute your actual username for username.

Note - It is not recommended to install OpenJDK under C:\Program Files\Java folder as this folder is used by Oracle JDK (commercially supported version).

Extracting OpenJDK Files

Create the OpenJDK parent installation folder and extract files from the downloaded ZIP archive there. If you need help with the ZIP files extraction, see an example in Appendix 12 – Extracting Eclipse Files to the Destination Folder.

Open the OpenJDK parent installation folder.

When the ZIP archive is extracted, it creates subfolder matching the OpenJDK version (jdk in the screenshot). Click on the subfolder to view it content.

In this example, the complete path to OpenJDK 11 is C:\Program Files\OpenJDK\jdk

Note – The created subfolder name contains JDK version, so you can install multiple versions of OpenJDK in the same parent installation folder. For instance, if you install OpenJDK 12, the subfolder will be jdk.

Enabling Eclipse Launching via OpenJDK

To be able to run Eclipse, Eclipse launcher has to know OpenJDK installation folder path. One way is to make OpenJDK default – to add OpenJDK bin subfolder to Windows PATH environment variable as described below.

If you do not want to use OpenJDK as default Java virtual machine, you can use one of the following approaches

Adding OpenJDK to Windows Path

After the OpenJDK files are extracted to an installation folder, consider adding its bin subfolder to Windows system or user PATH environment variable. Add OpenJDK to the system PATH if you want all users to be able to use it. Add it to the user PATH otherwise.

For example, add C:\Program Files\OpenJDK\jdk\bin to the system PATH variable. In the case of Windows 10, the Edit environment variable window will look like this

In the case of legacy Windows, the Edit System Variable window will look like this

If you need a detailed walkthrough, see Appendix 1 – Modifying Windows Environment Variables.

Access Environment Variables window, for example, by going to Windows Search -> “environment” -> Edit the system environment variables -> System Properties -> Advanced -> Environment Variables.

In the Environment Variables window, find existing system (or user) PATH variable or create new user PATH variable. Add the OpenJDK bin folders to the path variable.

Note - The user path is appended to the system path. In most cases, you need Cygwin to be added either to the system or to the user path variable.

Verifying OpenJDK in Windows Path

To verify Windows path, launch a command line window. For example, find or open the Windows search box and click inside it, then search for cmd program.

Enter word cmd① in the search field. Click on cmd② in the list of found programs.

You will see Windows shell (command line) window.

At the shell prompt, enter java -version command ① and press Enter key. You are supposed to see OpenJDK version information ②.

Note - there is a space between java and -version and one dash in the -version.

Eclipse IDE^🌐 is an integrated development environment that can be used to develop programs in a variety of programming languages, including Java and C/C++. For a good summary, check Wikipedia’s Eclipse (software)^🌐 webpage.

These instructions were prepared when the current Eclipse version was called “Photon”. If you download more recent Eclipse version, you may see some differences between the actual installation process and the process described in these instructions.

Selecting Eclipse Package

Depending on your needs, select what Eclipse packages to install. In this document, the following packages and components are covered

The total disk space mentioned above does not include space needed to store the downloaded Eclipse ZIP archives. Also note that you can install multiple packages at the same time as long as each package is installed in a separate folder.

You can see more information about available Eclipse packages on Compare Eclipse Packages^🌐 webpage. Eclipse packages consist of dozens of smaller components that can be combined and mixed. Such components can be called Eclipse add-ons, plugin, or just software items. If you decide to install additional Eclipse components, Installing CDT Add-on section and Appendix 4 – Managing Eclipse Software provide some examples.

For instance, you can install Eclipse IDE for Java Developers first and then add C/C++ Development Tooling to it (see Installing CDT Add-on section). Or you can install Eclipse IDE for C/C++ Developers first and then add Java Development Tooling to it (out of this document scope). In both cases, you will get Eclipse IDE capable of Java and C/C++ development.

Note 1 - C/C++ Development Tooling (CDT) is an add-on to Eclipse. If a mixed C/C++ and Java development is required, install Eclipse IDE for Java (or Java EE) first and CDT add-on second.

Note 2 - To run Java Enterprise programs an appropriate Java Enterprise Application Server is required (that is out of this document scope).

Eclipse Installation Folder

Decide where you want Eclipse to be installed to (the installation folder). You have two choices

1. If you are going to use Eclipse and nobody else – install it in your data directory, for example,
   C:\Users\Richard\Eclipse\java. You will not need an administrator access to manage Eclipse in this case.

2. If other users are going to use Eclipse – install it in the program folder or some other shared folder, for example, C:\Program Files\Eclipse\cpp. In this case, some Eclipse management will have to be performed using administrator access, specifically, (a) editing warwickbromleyfiles.co.uk file, (b) initializing Eclipse data, (c) installing Eclipse software, and (d) updating Eclipse.

The table below describes the destination folder selection. Substitute your actual username for username and appropriate installation name for java.

You can have multiple Eclipse packages and their versions installed, just use unique installation names.

For example, you can have java and java-photon. If you want to keep Java and C/C++ Eclipse installations separate, you can have java and cpp. Or you can have common installation eclipse.

Note – Usually the installation folder has exactly one eclipse subfolder that contains all Eclipse files. For example, C:\Users\Richard\Eclipse\java\eclipse. Sometimes, in Eclipse documentation, this subfolder is called “root folder”, it may be also called “installation folder”.

It may be confusing, but from the context it shall be easy to distinguish if “installation folder” refers to C:\Users\Richard\Eclipse\java or C:\Users\Richard\Eclipse\java\eclipse.

Eclipse Oomph Installer

Using Eclipse Oomph Installer^🌐 is the recommended way to install Eclipse. The installer makes it easier to select Eclipse software, download it, install it, adjusts some settings, etc.

Another option is to download and unpack Eclipse ZIP archive. If you are interested in it, see Appendix 16 – Installing Eclipse via ZIP Archive.

Downloading Eclipse Oomph Installer

In your browser open warwickbromleyfiles.co.uk^🌐

Click on orange

download button.

You will see Download Eclipse Technology^🌐 page

Click on orange

download button.

You will see Eclipse Installer Download^🌐 page (or similar page)

Click on orange

download button.

Depending on your browser, you will get a download prompt. Download and run the file. See Appendix 11 – Downloading and Running files from the Internet if you need help with the file downloading.

Simple vs Advanced Mode

When Eclipse Oomph Installer is started the first time, it runs in so called simple mode. If needed, the installer can be restarted in advanced mode.

Here is a summary of differences between the simple and advanced modes.

The simple mode is illustrated in Eclipse Installer in Simple Mode section, the advanced mode explained in Appendix 7 – Eclipse Installer in Advanced Mode.

Running Eclipse Installer the First Time

If you did not ask the browser to run the downloaded file, find Eclipse Oomph Installer executable (eclipse-inst-winexe) in the file explorer and run it.

If you see the following pop-up window,

it means that Java SE bin subfolder is not in the Windows PATH environment variable. You have two choices

• Press No button. Add Java SE bin subfolder to the Windows PATH environment variable as described in section Adding OpenJDK to Windows Path. Start Eclipse Oomph Installer again.

• Press Yes button. It will open a file browser window that you can use to locate appropriate Java SE virtual machine (specifically warwickbromleyfiles.co.uk file in Java SE bin subfolder). The installer will use this virtual machine to run itself and to configure Eclipse warwickbromleyfiles.co.uk file, so Eclipse will use it also. See Appendix 2 – Configuring Eclipse Lunch Properties (warwickbromleyfiles.co.uk) for more information.

You will see the following splash window

If you are running the installer the first time, you will be asked to accept its license

Review the license and press Accept Now button if you want to continue.

Eclipse Installer in Simple Mode

When you run Eclipse installer in the simple mode, you will see a window similar to one below

Select Eclipse package that you want to download and click on correspondent Windows bit link.

1. If you want to use Eclipse for C/C++ development only, select “Eclipse IDE for C/C++ Developers”

2. If you want to use Eclipse for Java standalone program development and, possibly, C/C++ development, select “Eclipse IDE for Java Developers”

3. If you want to use Eclipse for Java Enterprise development, possibly, for Java standalone program development, and, possibly, C/C++ development, select “Eclipse IDE for Java EE Developers”

Below it is assumed that “Eclipse IDE for Java Developers” is selected.

You will see the following page

Review the licenses. Check Remember accepted licenses box ①. Click Accept button ② to continue.

You will see the following window

Review the installation folder ①. If needed, enter a different name of or browse to a different folder ②.

If you do not want the desktop shortcut or the menu entry created, uncheck the appropriate boxes.

Press Install button ③ to continue.

You will see the installation progress window

While installing Eclipse CDT, the installer may prompt for Eclipse code signing certificate confirmation. You will have to accept the certificate to continue.

Review the certificate list (select a certificate and use Details button to see the certificate information). If you trust the certificate(s), check appropriate box(es) ① and press Accept selected button ②.

See Do you trust these certificates? in Appendix 13 – Eclipse Pop-ups and Prompts for more details.

After the installation is completed, you will see the following window

Close the window ②. How to launch Eclipse will be explained in further sections.

Note – if you are sure that Eclipse can find Java virtual machine, you may press Launch button ①.

Switching to Advanced Mode

To switch to advanced mode, start Eclipse installer in simple mode.

Click on “hamburger” icon ① to open the installer menu. Click on Advanced Mode…②.

See Appendix 7 – Eclipse Installer in Advanced Mode for a detailed walkthrough.

Setting Up Eclipse Shortcut

Having an Eclipse desktop shortcut (or a menu entry) makes launching Eclipse easier. By default, Eclipse installer in simple mode creates the shortcut (and the menu entry) automatically.

If you uncheck the shortcut option in the installer, or if you run the installer in advanced mode, the installer does not create the shortcut.

In such a case, you can create the shortcut manually. To do so, open the Eclipse installation directory in Windows Explorer, and go inside eclipse subfolder.

Move the mouse pointer over warwickbromleyfiles.co.ukicon and click the right mouse button to open a context menu. Depending on you File Explorer settings, you may see warwickbromleyfiles.co.uk or just eclipse right to it.

Select Copy from the menu. Find some empty space on your desktop, move the mouse pointer there, and click the right mouse button to open a context menu. Select Paste Shortcut from the menu. You will see a new shortcut eclipse icon with “warwickbromleyfiles.co.uk – Shortcut” (or just “warwickbromleyfiles.co.uk”) underneath.

Change the shortcut name to Eclipse Photon (or something else). Move the mouse pointer over the new shortcut icon and click the right mouse button to open a context menu. Select Rename from the menu. Enter the shortcut name in the highlighted box end press Enter key.

If you need more help, see section Creating Eclipse Desktop Shortcut in Appendix 6 – Making Eclipse Shortcut.

How Eclipse Launcher Locates Java Virtual Machine

Usually, to start Eclipse people run so called Eclipse launcher (warwickbromleyfiles.co.uk) via a shortcut, a script, Windows explorer, or a command line. The launcher determines what Java virtual machine to use and then starts the Eclipse application itself running in the machine.

If you followed Enabling Eclipse Launching via OpenJDK section, you can skip to the next section. Otherwise read this section and enable one of the options described in the table.

The Eclipse launcher searches Java virtual machines in the following locations, in the following order, starting at step 1.

If you use one of the options and later decide to switch to another one, pay attention to the order in which locations are searched. For example, if you have a -vm argument in an warwickbromleyfiles.co.uk file, added manually or automatically (by Eclipse Oomph installer), and you want to use PATH variable, the -vm argument has to be removed from the warwickbromleyfiles.co.uk file. Otherwise, the -vm specified Java virtual machine will be used, not the machine found in the Windows path.

Note 1 – The Eclipse launcher does not use JAVA_HOME environment variable.

Note 2 – See Eclipse Launcher^🌐 for more details.

Configuring Eclipse Lunch Properties

Eclipse launcher uses properties configured in warwickbromleyfiles.co.uk file that resides inside Eclipse installation folder. Sometimes, it might be necessary to change the properties, for example, to specify what Java virtual machine to use or how much memory to use.

If you use Eclipse Oomph installer, it may add Java SE bin subfolder pathname to the warwickbromleyfiles.co.uk file, as in the example below.

If you want Eclipse to run under a different Java SE virtual machine, exit Eclipse, if running, and edit this file - change the pathname, as described in Appendix 2 – Configuring Eclipse Lunch Properties (warwickbromleyfiles.co.uk), or remove these two lines completely. Additional details are provided in How Eclipse Launcher Locates Java Virtual Machine section later in this document.

Running Eclipse as Regular User vs Administrator

Running Eclipse as Regular User

If Eclipse is installed in a folder the user can write to (such as your user data folder) or if you are using Windows XP

Running Eclipse as Administrator

If you are using Windows other than Windows XP and Eclipse is installed in a folder that the user cannot write to, for example, C:\Program Files

See When to Run Eclipse as Administrator in Appendix 4 – Managing Eclipse Software for a walkthrough.

Initializing Shared Eclipse Installation as Administrator

To improve Eclipse performance, if Eclipse is installed in a folder that the user cannot write to, for example C:\Program Files\Eclipse\Photon, it is recommended to initialize Eclipse configuration data (such as caches).

If Eclipse is installed in a folder the user can write to, such as your user data folder, there is no need to initialize the configuration data (though it is safe to do so).

To initialize the data, it is enough to start Eclipse as Administrator, as described in the next section. While running Eclipse as Administrator, do software updates (if needed), fix Java SE 11 issues (if needed), install CDT Add-on (if needed). After it, exit Eclipse and then start it again as regular user.

Note – You can also initialize the data if you run warwickbromleyfiles.co.uk with -initialize option as Administrator. If you are interested in this option, see Initializing Shared Eclipse Installation via Command Line in Appendix 4 – Managing Eclipse Software.

Launching Eclipse

If Eclipse Launcher is already Running

You have to exit the launcher if it is running as regular user but you need it to run as Administrator, and vice versa. To exit the launcher, press Cancel button.

If Eclipse Launcher is not yet Running

If you are going to run Eclipse as regular user,

If you are going to run Eclipse as Administrator,

Launcher Process

The launcher will figure out what Java virtual machine to use if you added Java bin subfolder to Windows path or enabled one of the options explained in Enabling Eclipse Launching via OpenJDK and How Eclipse Launcher Locates Java Virtual Machine sections.

Then the launcher will start the Eclipse application using the found Java virtual machine.

When the launcher is running, you will see a splash window.

After the splash window you will see Eclipse IDE Launcher window.

You can use the suggested workspace folder path. If you do not like it, enter whatever workspace folder path you prefer. The workspace folder contains all files related to your development projects (source code, data files, binary files, etc.). You can have multiple workspaces (for example, all java projects in one workspace, and C++ projects in another workspace). Each workspace has own set of preferences, so you can customize the workspaces to your needs.

Selecting Workspace when Run as Regular User

Enter the workspace folder name in Workspace field ①. For example, add \Java to the pathname. Use Browse button ② to select the folder, if needed.

Press Launch button ③ to start the Eclipse. Press Cancel button ④ if you want to exit the Eclipse.

Selecting Workspace when Run as Administrator

If the Eclipse is run as Administrator, we recommend creating a dedicated administrative workspace.

Enter the administrative workspace folder name in Workspace field ①. For example, add \Admin to the pathname. Use Browse button ② to select the folder, if needed.

Press Launch button ③ to start the Eclipse. Press Cancel button ④ if you want to exit the Eclipse.

Note – The workspace folder will be owned by Administrators. It shall be used for Eclipse software management and for testing. Some Eclipse functionality might not work if the workspace is used by a regular user. See When to Run Eclipse as Administrator section in Appendix 4 – Managing Eclipse Software.

Starting Eclipse Application

After Eclipse launcher figures out what Java virtual machine to use and what workspace to open, it starts the Eclipse application itself.

You will see Eclipse application splash window.

After few seconds you will see a welcome window. The specific window depends on the installed Eclipse variant – Eclipse IDE for Java, Java EE, or C/C++ Developers.

When the Eclipse is finally started, you will see a Welcome (also called overview) pane similar to one below

In this screenshot, the overview contains a mix of C/C++, Java, and PHP information because I installed C/C++ and PHP plugins in addition to basic Java Enterprise Eclipse variant.

What you see in the Welcome pane depends on the Eclipse variant and additionally installed Eclipse software.

Click on “Minimize” icon inside Eclipse window to minimize the Welcome pane. As a side effect other, previously minimized, elements of Eclipse interface will become visible.

Sometimes, after the start, everything is minimized as in the example below

In such a case, click on “Restore” icon inside Eclipse window to restore (unminimize) it.

First Software Update

If you used Eclipse Oomph Installer, there is no need to update the software at this point (the installer does it automatically). Skip to the next section in such a case.

If you used ZIP archive to install Eclipse, after Eclipse is installed and run the first time, it is recommended to update the Eclipse software. See Updating Eclipse Software (in Appendix 4 – Managing Eclipse Software) for the detailed walkthrough.

If needed, close Eclipse, start it again as Administrator, and select administrative workspace.

Open Help menu and select Check for updates. If the updates are found, Eclipse will display Available Updates window.

Be sure that all desired updates are selected and press Next button. Review the list of updates one more time, press Next button again to continue. Review the licenses, check I accept the terms of the license agreements, and press Finish button to continue.

Finally, after the software is updated, you will see a prompt asking to restart Eclipse. Press Restart Now button and wait until the Eclipse is restarted.

If Eclipse is running as Administrator and you do not intend to install any additional Eclipse software - press No button instead, exit Eclipse, and start Eclipse again in regular way, if needed.

Java SE 11 Issues

If Java SE 11 is used to run Eclipse IDE for Java Developers, you may experience issues mentioned in this section. It is also possible that the issues are resolved in the Eclipse version that you use.

How to check and fix the issues is described below.

Note - If you used ZIP archive to install Eclipse, try first to update Eclipse software as described in the previous section.

‘Features may not work as expected’ Issue

If Java SE 11 is used to run Eclipse IDE for Java Developers, you may see warning message “You selected a JRE that this version of Eclipse JDT does not yet support fully. Some of the features may not work as expected.”

You can disregard this message if you are not going to use Java SE 11 new features in your source code. See Java 11 Support in Eclipse^🌐 for more information about the features. If you want to use them, install Eclipse software items as detailed in Installing Java SE 11 Support Patch section.

To check if you have this issue, in Eclipse, open Window menu and select Preferences option.

You will see Eclipse preferences window.

Click on a small white triangle(or angle ) left to “Java” to open Java preferences. If you do not see the (tri)angles, move the mouse pointer to the left (white) panel and the (tri)angles will appear.

In the Java preferences ①, select Installed JREs②.

You have the issue if you see the warning ③“You selected a JRE that this version of Eclipse JDT does not yet support fully. Some of the features may not work as expected”.

Press Cancel button ④ to close the preferences.

Installing Java SE 11 Support Patch

If needed, close Eclipse (open File menu and select Exit option), start it again as Administrator, and select administrative workspace.

Open Help menu ① and select Install Additional Software option ②.

You will see Available Software window

On the Available Software page, press Manage button.

You will see Available Software Sites preferences.

Press Add button to add a new software site. It will open Edit Site pop-up window.

In the Name field ① enter

Java 11 Support

In the Location field ② enter

warwickbromleyfiles.co.uk

Press Add button ③ to add the site and to close the pop-up window.

You will see an updated list of software sites.

Press Apply and Close button to save and close the preferences.

You will be returned to the Available Software window.

Open ① the drop-down list of software sites. Select Java 11 Support site ②.

Wait until the software list is processed.

Click on white triangle (or angle ) left to Eclipse Java 11 support…① to open a list of software items in the group.

Check Eclipse JDT (Java Development Tools) Patch with Java 11 support… item ②. Press Next button ③ to continue.

Press Next button (if there is no Next button but there is Finish button, press Finish button).

Review the license and select option I accept…①. Press Finish button to proceed. The installation progress status will be displayed at the Eclipse main window bottom.

Wait until the software is installed.

Press Restart Now button ① and wait until the Eclipse is restarted if

• Eclipse is running as regular user and the current workspace is to be used for Java development

• Or Eclipse is running as administrator and you intend to do more Eclipse software management as administrator

Otherwise press No button ② instead, exit Eclipse, and start Eclipse again (and create Java dedicated workspace, if so desired).

Note – As long as Java 11 Support site is enabled in Available Software Sites preferences, the Java 11 patch will be shown in the list of available updates every time, does not matter that it is already installed. It is annoying but harmless. To remove the patch from the list, disable (uncheck) Java 11 Support site in the preferences.

Eclipse is (Almost) Done

I you installed Eclipse for Java (or Java EE), at this point, the Eclipse is (almost) ready for Java (and, possibly, Java EE) development but not for C/C++ development.

If you installed Eclipse IDE for C/C++ Developers, at this point, the Eclipse is (almost) ready for C/C++ development but not for Java development.

• You still need to install Cygwin (or another build system) to be able to compile, link, run, and debug C/C++ applications. Proceed to Installing Cygwin section.

• If you want to develop Java programs, Java Development Tool kit (JDT) add-on has to be installed. The installation of JDT add-on is out of scope of this document. It, though, is very similar to installation of CDT add-on described below in Installing Eclipse C/C++ Development Tooling (CDT) section.

Eclipse C/C++ Development Tooling (CDT)^🌐 is an add-on to Eclipse IDE. It is a part of Eclipse IDE for C/C++ Developers, so you do not need to install CDT if Eclipse IDE for C/C++ Developers is installed.

If you have Eclipse IDE variant other than Eclipse IDE for C/C++ Developers and want to do C/C++ development, you will have to install CDT add-on.

CDT add-on consists of multiple Eclipse plugins, the recommended minimum is listed below (It will take approximately 58 MiB of disk space).

• “C/C++ Development Tools”

• “C/C++ Library API Documentation Hover Help”

• “C/C++ Unit Testing Support”

• “TM Terminal”

• “Mylyn Context Connector: C/C++ Development”

For a complete list of software items in CDT add-on, see Appendix 10 – List of Software Items included in Eclipse CDT. Review them and install as needed.

Installing CDT Add-on

If needed, close Eclipse (open File menu and select Exit option), start it again as Administrator, and select administrative workspace.

In the Eclipse window, open Help menu, select Install New Software option.

You will see Available Software window

Check Hide items that are already installed① if it is not checked already. Click small (tri)angle left to Add button ② to open a menu of software “sites”.

Select All Available Sites option and wait. It may take few minutes for Eclipse to process required data.

Selecting Software Items to Install

Scroll down until you see Programming Languages group. Click on white triangle (or angle ) left to “Programming Languages” to open a list of software items in the group.

If you are installing Eclipse Photon (or Juno, or any later version) check items listed below

“C/C++ Development Tools”
“C/C++ Library API Documentation Hover Help”
“C/C++ Unit Testing Support”

If you are installing Eclipse Indigo check items listed below

“C/C++ Development Tools”
“C/C++ Library API Documentation Hover Help”

If some item is mentioned twice, select one that has newer version.

Scroll up until you see General Purpose Tools group. Click on white triangle (or angle ) left to it to open a list of general software.

Check “TM Terminal” item if you see it. By default, already installed items are not shown. So, if you cannot “TM Terminal” item, it is already installed.

Scroll up until you see Collaboration group. Click on white triangle left (or angle ) to it to open a list of collaboration software.

Check “Mylyn Context Connector: C/C++ Development” item.

You can also search for software. For example, if you enter C++ in the search field, after some delay, Eclipse will display C++ related items (can be slow).

Select additional items, as desired.

Finishing CDT Installation

When all needed items are selected, press Next button to proceed with the installation.

It is possible that some of the selected software items cannot be installed (for example, C/C++ Call Graph Visualization is not available for Windows). In such a case, you will get “Install Remediation Page” as below (otherwise just skip to the next page).

If you select option “Keep …” ① and press Next button ②, the wizard will install items that it can. You can also press Back button to return to the previous wizard page and change the list of items there.

Selecting other option but “Keep…” ① is outside of this document scope.

You will see Install Details window.

Inspect the list one more time and press Next button to continue (or Cancel button to stop the installation).

You will see Review Licenses window.

Review the licenses. Check I accept the terms of the license agreements① and press Finish button ② to continue (or press Cancel button to stop the installation).

At the bottom of the main Eclipse window, you will see progress message “Installing Software …”

Wait until the installation is completed.

If some software is unsigned (by its developers), you may see various security prompts. See Appendix 13 – Eclipse Pop-ups and Prompts for more details.

Finally, after the plugins are installed, you will see a prompt asking to restart Eclipse.

Press Restart Now button ① and wait until the Eclipse is restarted if

• Eclipse is running as regular user and the current workspace is to be used for Java development

• Or Eclipse is running as administrator and you intend to do more Eclipse software management as administrator

Otherwise press No button ② instead, exit Eclipse, and start Eclipse again (and create Java dedicated workspace, if so desired).

Wait until the main Eclipse window appears. If everything is minimized, click on “Restore” icon inside Eclipse window to restore (unminimize) it.

Eclipse CDT is installed, but you need to configure it before using.

In this screenshot, you can see that the Eclipse window title is “CPP2 – Java”. It is just an example. In the title, CPP2 is the workspace name and Java is the perspective name. When you do C/C++ development, you will, probably use C/C++ perspective (as described later in section Opening C/C++ Perspective).

Cygwin development packages are required in order to be able to compile, link, build, run, and debug C/C++ programs. You will need approximately 10 GiB of disk space to install all Cygwin development packages (you can reduce the disk space by not installing unnecessary development packages). You also will need around GiB of temporary disk space to store downloaded Cygwin packages.

Downloading Cygwin Setup Program

In a browser, open warwickbromleyfiles.co.uk^🌐 website.

Click on setup-x86_exe^🌐 URL (see Cygwin bit if you are running bit Windows). Depending on your browser, you will get a download prompt. Download and run the file. See Appendix 11 – Downloading and Running files from the Internet for more information.

Running Cygwin Setup Program

When you run the downloaded Cygwin setup program, you will see the following window.

Press Next button to continue.

Be sure that “Install from Internet” option is selected. Press Next button.

The next screen will ask to select root install directory.

Default settings are OK. By default, Cygwin is installed in C:\cygwin64 on bit Windows. You can change this path in the Root Directory field ① if you prefer Cygwin files to be installed in another folder. Press Next button ② to continue.

You, probably, will want to change Local Package Directory field ①. The folder will be used to store so called package files. These package files are used to install Cygwin features; they are not needed after the installation.

For example, click right to the highlighted folder path ① and edit it so the packages go to C:\Users\username\Dowloads\Cygwin. Press Next button ②.

You can keep these files if you expect to reinstall Cygwin or to install Cygwin on a different computer. Or you can remove the folder after Cygwin is installed.

If the directory does not exist, you will see a pop-up window asking to confirm the directory creation.
