Eclipase 无法启动，启动界面显示完版本号之后无响应
解决方法：
首先、Open your workspace.metadata.log file. That will tell you usually what is going wrong.
而我的错误是：
!ENTRY org.eclipse.core.resources 2 10035 2013-11-21 12:19:34.443
!MESSAGE The workspace exited with unsaved changes in the previous session; refreshing workspace to recover changes.
解决办法是：
找到：workspace/.metadata/.plugins/org.eclipse.core.resources/.snap
delete .snap.
(then import your project again),我的打开之后，项目还可以用。
