Repair eclipse workbench – corrupted eclipse workspace

My workbench often gets corrupted, and all good advice on the net does not work, since the hints there are based on the fact, that eclipse starts up. But what happens, if eclipse refuses to start due to the corrupted workbench (the usual situation I have)?
First of all, check the log message. You’ll find your eclispe-log in your workbench-folder. It’s named “.metadata”. In this folder you’ll find a file called “.log”. Open this file and see if you can get some usefull information from there. Here is the file I just got today:

The usefull information in this special case is: org.apache.commons.lang.exception.NestableError: Java Model Exception: Java Model Status [src/net/project/windows [in project] does not exist] for any reason, eclipse can not open a special file on the workbench. After several tries I found a way to solve this problem:
- Make a backup of your “.metadata“-folder (very important!!)
- navigate into the “.plugins“-folder located inside “.metadata“
- delete the folder “org.eclipse.ui.workbench“
- startup eclipse again and check if there is still everything you need
Hint: BackUp your complete workbench often!
Please keep in mind: You use this advice at your very own risk
