After installing JDK9 my eclipse stopped working [duplicate] - eclipse

Question

Today I downloaded Eclipse Neon. When I ran it for the first time it asked me to select a folder as my workspace. After doing this it throws me an error which redirects me to a log file inside the folder I selected to save my workspace:

Sorry for the long post. Any ideas?

Answer 1

You are starting Eclipse using Java 9. This currently does not work with recent builds of Java 9.
Eclipse bug 493761 describes this problem and is currently scheduled to be fixed in Eclipse 4.6.2 (Neon.2)
Until Eclipse 4.6.2 is available use a Java 8 JDK to run Eclipse.
Update:
To run Eclipse with Java 9 you need to modify the 'eclipse.ini' file in your Eclipse installation and add the line:
--add-modules=ALL-SYSTEM
as a line following the -vmargs line in the file. This adds the Java 9 module containing the missing classes.
Eclipse Oxygen.1a (4.7.1a) due for release on 11 October 2017 will have full Java 9 support.
Also see Configuring Eclipse for Java 9 in the Eclipse wiki.

Answer 2

Made it to work in OSX Sierra by adding the following:
--add-modules=java.se.ee
at the end of eclipse.ini

Answer 3

Works for me using the most recent Java 9 early access build b143 and Neon Release 4.6.0
Just add
--add-modules=java.annotations.common
to the eclipse ini after -vmargs

Answer 4

Adding --add-modules=java.se.ee, after -vmargs in STS.ini or eclipse.ini will solve the launching issue.
-vmargs
--add-modules=java.se.ee
-Dosgi.requiredJavaVersion=1.8
-Xms40m
-Dosgi.module.lock.timeout=10
-Xverify:none
-Dorg.eclipse.swt.browser.IEVersion=10001
-Xmx1200m
refer to the link: https://bugs.eclipse.org/bugs/show_bug.cgi?id=493761 for more information

Answer 5

I've just had same issue today, the issue in my case was because I was using jdk 11, good tip about the eclipse.ini file, in my case it was indicating clearly it was expecting to use jdk 8, downloaded that version, replaced the jdk path in the env params and it is working now.
