Answer 1

you should delete

1) ...\workspace.metadata.plugins\org.eclipse.e4.workbench"

and tell me about the status.

2) There's a .log file in the .metadata directory inside each workspace, which often contains a number of stack traces from the Eclipse internals. Startup crashes are usually found here. I'm assuming you have Eclipse configured to start up in a specific workspace automatically, without prompting you to pick one at startup.

3) add this in eclipse.ini:

-vm C:/Program Files/Java/jdk1.8.0_5/jre/bin/javaw.exe And it can work. I change the JRE to JDK/JRE.

JAVA_HOME and JRE_HOME Should point to the above location.

Try these methods one by one.. One of them will work. this is like a troubleshooter.
