Launching Eclipse 4.7 with Java 9: You have downloaded an early access version of Java 9 and would like to launch eclipse Oxygen 4.7 with this version. This page describes how to do this. Since Java 9 comes in a modularized form, some initial configuration needs to be done in the eclipse configuration file eclipse.ini.
add the following lines (without the quotes) in eclipse.ini file
- add -vm <path to java> : for example "-vm D:\JDKs\jdk-9-ea+169_windows-x64_bin\jdk9\jdk-9\bin\" - This is the standard procedure for running with any JDK other than the standard on
- Add the line "-vmargs" if not present
- Under -vmargs, add "--add-modules=ALL-SYSTEM". By now, if you should be able to launch eclipse.
- If you encounter an exception such as IllegalAccessException or InaccessibleObjectException, add "--permit-illegal-access" additionally after the -vmargs.
A sample eclipse.ini file with the relevant parts highlighted in bold is given below :
-startup
plugins/org.eclipse.equinox.launcher_1.4.0.v20161219-1356.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.500.v20170531-1133
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vm
D:\JDKs\jdk-9-ea+169_windows-x64_bin\jdk9\jdk-9\bin\
-vmargs
--add-modules=ALL-SYSTEM
--premit-illegal-access
-Dosgi.requiredJavaVersion=1.8
-Xms256m
-Xmx1024m
Please note the following:
- Repeating that this page describes just how to use a Java 9 JDK to launch eclipse 4.7 - nothing more and nothing less.
- Java 9 features are not shipped standard with 4.7, you need to install that separately from MarketPlace
- You need not launch eclipse with a Java 9 JDK to build Java 9 code in Eclipse; you can still launch with JDK 8, but use the patch for Java 9 from the above link.
- Java 9 is still in early access, and hence the options are yet to be stable. It is possible that the info given here will change over time. Currently verified with Java 9 EA 169.
