Eclipse 启动不了 一闪而过


问题描述】：

我的WTP版Eclipse，点击Eclipse图标启动，然后进度条进行一会，就一闪而过，消失了。即便你从新解压个新的eclipse也同样也是失败的。

【问题分析】：

命令行跟踪下启动log，Ctril+R然后cmd到Eclipse的安装目录，接着输入eclipse.exe启动，log如下：

当然聪明的你到/.metadata/.log文件下也是可以看到错误信息的，摘录如下：

【问题解决】：

log分析下应该是可以看出端倪，就是进程没被kill干净，导致平台数据状态不一致。

方法一：

删除，workspace目录下的.metadata，有后遗症的，有些eclipse插件会出现问题。（不推荐）

方法二：
删除，workspace目录下的
/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi
假如还不行，顺便把这个/.metadata/.plugins/org.eclipse.core.resourses/.snap也删掉。
