myeclipse 2014无法启动解决方法

      今天一打开myeclipse 2014就自动关闭了，重启电脑多次尝试都无法启动，在myeclipse的工作空间目录：WorkSpace\.metadata文件夹中发现启动日志.log文件中有报错信息：

         拿这个几个错误日志到网上搜了一下，有各种解决方法，大部分都解决不了我这个情况。找到最后发现将工作空间目录：workspace\.metadata\.plugins\org.eclipse.e4.workbench\workbench.xmi 这个文件删除就好了 .

其他的说重装，删除工作空间之类的解决方案代价都太大，耗时，这个是最简单的处理方案。
