重型当一个吧，反正免费的

[myth822]

几点建议
1 删除eclipse目录下的configuration文件夹，重启
2 删除eclipse目录下的对应的org.eclipse.core.resources（不知道是否有），重启
3 重新装一个，配置很简单，推荐！！

[mengfanpp]

重新装一个

[redex]

删除eclipse的workplace目录和第一次启动时生成的目录
重新启动eclipse.

[snowfox_yy]

redex(cc) 的回答我赞同，一定能行。

[halloo]

重新装也没用，同样是报错，好像3.0rc1,rc2都有这个问题，大家再帮我看看下面的错误

[halloo]

这个错误我是在写程序的时候切换工作空间造成的，各位大大是不是也出现过同样的问题。

[xitianjile]

删除workplace目录。
打开进程管理器。
关掉与JAVA相关的进程。
重新启动。

[halloo]

还是不行，怎么办啊，不会要我重新装系统吧
