Eclipse崩溃后无法启动的问题解决

次Eclipse发生内存溢出（ADT环境，多打开几个xml文件内存占用就会飚升），强制结束任务，再次启动Eclipse发现闪退。查看workspace/.metadata/.log文件发现如下错误信息：

!ENTRY org.eclipse.equinox.p2.ui.sdk.scheduler 4 0 2015-04-07 22:29:38.086

!MESSAGE Unable to execute early startup code for an extension

解决方法是删除workspace/.metadata/.plugins/目录下的org.eclipse.equinox.p2.ui和org.eclipse.e4.workbench这两个文件夹，之后启动Eclipse恢复正常。
