Eclipse Hellios 3.6 - eclipse

Question

I have installed Google plugin on Eclipse 3.6, but I can't create web applications because of an error (and a large error log file is created). What is reason for these errors?
Here was a full list, but I have deleted it because of the maximum 30000 characters. I have left this part:

Try restarting eclipse with "clean " option . From the command-line execute "eclipse.exe -clean".
