How do I fix java was started but returned exit code?

If you have installed 64 bit version of java jdk and 32 bit version of eclipse ide or vice versa , then you will get this error. You will get rid of this error by just downloading the correct version of java jdk and eclipse ide.

JUST DELETE WORKSPACE(S) I had the same problem and its easily solved by deleting the my Workspace folders, in Eclipse --> File --> Switch Workspace ,I found the location of my Workspaces and I went to the direction and deleted them, after I did this my problem solved :)
