(Eclipse)How to resolve "Initializing Java Tooling"

Just met an initialization error on Eclipse, the error message is:

'Initializing Java Tooling' has encountered a problem. An internal error occurred during: "Initializing Java Tooling".

It's really annoying, after googling several sites, here is a working solution:

Delete the following directory: WORKSPACE_HOME/.metadata/.plugins/org.eclipse.core.resources/.project, and restart Eclipse and problem should be solved.

 经本人测试，确实可以解决这个问题，但是删除那个目录以后，项目的SVN就断开了，所以又把该目录还原了，还原后也没有出现这个问题了，建议删除时做下备份
