Jdk For Eclipse Oxygen

A Java 8 or newer JRE/JDK is required to run all Oxygen packages based on Eclipse 4.7, including running the Installer. The reasoning behind requiring Java 8 are discussed here. Eclipse 4.7 (Oxygen) Eclipse 4.7 (Oxygen) was released on June 28, 2017. Eclipse Oxygen; Eclipse Installer; Eclipse Packages; Eclipse Developer Builds.

This wiki page explains how you can configure Eclipse to launch with Java 9. This also explains how the Java 9 support can be installed for Eclipse 4.7. Java 9 reorganizes the runtime into modules, but this conflicts with the way Eclipse organizes its own runtime.

Users who install Eclipse Oxygen 4.7.1a are able to launch with Java 9 and get Java 9 support, and the configuration described below won't be necessary anymore. There might be cases which won't work, see item 3 below in that case.

Download Java 9

You need to download and install a Java 9 VM, e.g. from http://jdk.java.net/9. If you are developing Java applications, or are on macOS, you should definitely get the JDK.

Configure Eclipse to run on Java 9 VM

If Java is automatically found when launching Eclipse, you need to specify the location of your Java VM. If you already do this, simply replace it with a Java 9 VM. Otherwise it can easily be done by adding something like:

following the --launcher.appendVmargs line to the eclipse.ini.

Configure Eclipse for Java 9 modules

Since the Eclipse SDK uses types that aren't in the java.base module, you need to add the following vmargs to eclipse.ini:

Your project might fail to run because you use types that are neither in java.base or java.se.ee, e.g. types from javafx.base. In that case you have to figure out which module(s) you need to add with --add-modules.

  • Only works in JDK 8, but not in JDK 9: Run jdeps fully.qualified.classname
  • In Eclipse with Java 9 Support for Oxygen (see below), you can open the type in a JavaSE-9 JRE and perform Show In > Package Explorer. Inside the 'JRE System Library' node, the Package Explorer will show the module in which that type resides.

Your eclipse.ini should contain something like:

Each argument must be on its own line, and every line after-vmargs is passed as an argument to the JVM. Incorrect arguments after the -vmargs line often cause the JVM to exit immediately.

Install Eclipse Java 9 Support for Oxygen releases before Oxygen.1a

This is useful if you have to debug problems, e.g. when it fails to run your project.

This is essential if you want to run JUnit tests in the Eclipse IDE using Java 9.

We recommend to install the support via Eclipse Marketplace because it is crucial that the Eclipse install, the Java 9 VM and the patch match. If you are not using an EPP with a pre-installed Marketplace Client, you must install it first (from the General Purpose Tools category of the http://download.eclipse.org/releases/oxygen P2 repo).

Another way to install it is to use Ed's Oomph based installer described here: https://dev.eclipse.org/mhonarc/lists/cross-project-issues-dev/msg14178.html.

Specify a Java 9 JRE

Download Jdk For Eclipse

Use Window->Preferences->Java->Install JREs to make your Java 9 VM available within Eclipse.

You may want to associate Java 9 with some Execution Environments to force a rebuild using Java 9.

Eclipse Set Jdk

To use Eclipse (4.7 Oxygen, 28 June 2017) you will need to have Java 8 installed, JAVA_HOME pointed to its main folder (e.g. C:Program FilesJavajdk1.8.0_45) and the PATH environment variable pointed to its bin sub folder (e.g. C:Program FilesJavajdk1.8.0_45bin).

Your path may also contain “C:ProgramDataOracleJavajavapath”, you may need to remove this delete the java executables in that add the bin folder before this in the path.

Once Eclipse is opened and your workspace initialised take the following steps to switch back to Java 7. If you do not do them all you may see an error like “Version 1.7.0_80 of the JVM is not suitable for this product. Version: 1.8 or greater is required.”

How To Install Jdk For Eclipse Oxygen

    1. Change JAVA_HOME back to the Java 7 folder (e.g. C:Program FilesJavajdk1.7.0_80)
    2. Change the Java path bin to Java 7 (e.g. C:Program FilesJavajdk1.7.0_80bin)
    3. In Eclipse go to Window -> Preferences -> Java -> installed JREs and select the Java 7 jdk folder
    4. In Eclipse go to Window -> Preferences -> Java -> Compiler & select Java 7
    5. With Eclipse closed open the eclipse.ini & add the following line for your appropriate Java 8 directory. Without this final step I still got the incompatible message:
      • -vm C:Program FilesJavajdk1.8.0_45bin
