my eclipse stopped working today

Question

Today I was running into problems with eclipse, like every time I closed a project a window popped up saying something like "error saving workspace" and complaining about apache xerces.

I decided to download a fresh install, and now it won't even start. I tried many variants (classic, javase, c++), hoping there was some distribution issues, but nothing worked. Eclipse starts saying "an error has occurred, see configurationlog ..."

Any idea? Are there some cached files in the system that might have become corrupted? I tried doing a "find / | grep eclipse" but found nothing interesting.

Thanks a lot for your help, I'm quite in trouble without it

ps I tried also with 32 bit jvm but nothing changed

[edit] here is relevant bits of the log produced when starting:

and several other mostly related to xml ...

Answer 1

Sounds like your current workspace is severely broken. Create a new workspace and import the projects from the old locations (File -> Import), and see if that helps.

我要尝试的工作是重命名工作空间（因此Eclipse在启动时将使用一个新的工作空间）或使用-clean参数运行Eclipse（在控制台中，在eclipse/文件夹中使用./eclipse -clean ）。
