Eclipse强制关闭导致无法再次启动的解决方法

Eclipse强制关闭后，重新再启动时，发现eclipse无法再次启动

查看workspace的.plugin文件夹下的.log文件，报错如下：

!ENTRY org.eclipse.ui 4 0 2017-11-14 23:55:00.898

!MESSAGE Error occurred during status handling

!STACK 0

解决方法1：删掉整个eclipse的workspace，但这样会导致之前建立的项目都不见了，得重建

解决方法2：删除org.eclipse.ui.workbench，这样也可以重启，目前没有看到这样解决会有什么隐患。
