Question

Just started playing with jdk9 - and kind-of stuck right at the beginning:

• downloaded and extracted eclipse-java-neon-m4a-win32
• installed java 9 supp

Answer 1

Whoever is facing the same Eclipse crash issue with the Java 11, none of the above solutions seem to work.

Here is the error:

org.eclipse.e4.core.di.InjectionException: java.lang.NoClassDefFoundError: javax/annotation/PostConstruct

As mentioned here https://bugs.eclipse.org/bugs/show_bug.cgi?id=533390, this issue is fixed with the Eclipse Photon 4.8.

Here is the workaround mentioned https://bugs.eclipse.org/bugs/show_bug.cgi?id=533390#c22. However, this just a short-term workaround so it's better to update the eclipse to 4.8

Steps:

1. Go to eclipse config.ini file, which you find here /Applications/Eclipse_4.7.2 .app/Contents/Eclipse/configuration/config.ini
2. Add the below content

Answer 2

Add the following line at the end of eclipse.ini

--add-modules=java.se.ee

Answer 3

I have the same error I find solution from Configure Eclipse for Java 9

Following edit you have to do in eclipse.ini file

1. -vm C:\Program Files\Java\jdk-9\bin\javaw.exe
2. --add-modules=ALL-SYSTEM

And It will solve your problem. Your eclipse.ini file look like following:

--launcher.appendVmargs
-vm
C:\Program Files\Java\jdk-9\bin\javaw.exe
-vmargs
-Dosgi.requiredJavaVersion=1.8
--add-modules=ALL-SYSTEM

Answer 4

To get rid of the java.lang.ClassNotFoundException: javax.annotation.PostConstruct issue, try adding the following line under -vmargs in your eclipse.ini:

-Djdk.launcher.addmods=java.annotations.common

(Will change to --add-modules=java.annotations.common in JDK 9 EA build 132)

See https://bugs.eclipse.org/bugs/show_bug.cgi?id=493761

UPDATE: Since this answer, more things changed, I am currently running Eclipse with JDK 9 b177 and these added vmargs: --add-modules=java.xml.bind,java.xml.ws.annotation

Answer 5

I had the same issue. The NoClassDefFoundError shows when you select to build/compile your project with Java 9 JDK. Eclipse is unable to find a required jar file in root JDK folder, so it fails to start completely. After installing the Java 9 support plugin from the marketplace you may be able to start Eclipse, but still you will see a lot of errors and won't be able to compile a single project. The solution (for now) is to switch to Java 9 JRE in "Installed JREs" under "Project Preferences". This fixed everything for me
