This happened after I made a system restore which (I think) reverted a java update. How do I solve this? I have a tun of stuff in eclipse and I don't want to redo it all again.

ADD:
Meanwhile I got Juno and it seems to be working. But, on my PC, juno has some issues with the shortcut keys and with about 12 plugins I use (they didn't update yet). Does this information help?

Answer 1

Steps to follow Open eclipse.ini file You can see below 2 line :

--launcher.defaultAction openFile

Now add below lines mention between Blockquote to set vm properly as per you jdk version

Blockquote

-vm

C:\Program Files\Java\jdk1.7.0_79\bin\javaw.exe

-XX:-UserCompressedOops

-vm

C:\Program Files\Java\jdk1.7.0_79\jre\bin\server\jvm.dll

Blockquote

before -vmargs

Answer 2

Finally I did it!

I updated java, rebooted, then uninstalled java, rebooted then installed java.

(rebooting was essential, I tried without rebooting and it didn't work)

now it's working as it should.

Answer 3

It seems that Eclipse is using java 1.7. Try to run Eclipse with a different vm. Install java 1.6 and edit the eclipse.ini adding the correspondent argument below, as described here

-vm C:\Java\JDK\1.6\bin\javaw.exe

Answer 4

Backup your .metadata folder, delete it, and try to start Eclipse.
