Eclipse crash and cannot open

Question

I was running an application for a long time while suddenly eclipse crash and until now cannot open. I am using Win 7 O.S and java 7. I have never set the HOME variable while Eclipse was working perfectly. After Eclipse crashed i set up the HOME_JAVA but the problem is the same.I cannot open eclipse from the workbench.

My Metadata file has the below lines.

!SUBENTRY 1 org.eclipse.equinox.registry 4 1 2014-06-03 10:39:07.782

Can anyone help me how to solve that issue??

Answer 1

There is no need to remove the entire your-workspace/.metadata/.plugins directory.

Just remove the file your-workspace/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi.

This stores the list of files opened in the workbench, one of them (very likely a pom.xml) is causing the problem you're experiencing.
