Disable plugins on Eclipse startup

Question

I just installed a plugin for Eclipse, but as a result Eclipse will no longer start. It says \"There was an error\" or some such uninformative message.

How can I start E

Answer 1

Try to start eclipse with the -clean option.

Or try to delete move the pluings and the features.

Posting the error-message is more useful than "there was an error". Look into the logfile or try to start from the console and post the error message here.

Edit: Irbull is right. Of course don't delete the files, just move them in another directory so you can move them back. His solution sounds very helpful and is even more professional.
