[yaku2688]

以前还能正常启动 但不知道怎么会事现在启动不了了 Eclipse For Java

双击图标后选择工作空间 然后它一闪就没了，打开日志报些这样的异常 大侠们帮忙看下怎么会事

是的啊，我都是重新解压了，还不行，而且又到官网下了个新的，还是报这个错误。而Eclipse JEE版本的就没问题

[wuzg光]

把系统文件删干净了再重新安装

[jio891250]

把有关eclipse的文件完全删除后重新安装下。

[yaku2688]

它产生的相关文件都有哪些呢？

!MESSAGE Unhandled event loop exception
是不是不小心把Eclipse的某些系统文件删了

实在不行就重新装一个吧，还是这样快

[yanebupt]

只重装eclipse还报错的话，就把jdk和eclipse都重新安装

[老廉颇尚能饭否]

很简单，重新解压缩一个。

[dev.xiaowangye]

把workspace文件夹下的.metadata文件删了就好了。

哦哦 找到原因了 是Win7权限惹的祸 C盘文件权限有问题
