What can I do to fix this?

I have faced problem related to this not exactly this but something related

so you should re-install your jdk and jre in your system and then run eclipse, if the same not resolved then try to re-install eclipse again because some times the plug in files are corrupted due to any reason

so you should try this

Nothing worked so I just installed MotoDev and it all works now.
