打开时eclipse juno出错
安装Eclipse并运行一年多之后，我今天打开了Eclipse Juno，并在打开工作区时收到错误消息。 我使用的是Windows 8 64位，Java 64位和Eclipse 64位。 我已经尝试重新安装Java和Eclipse而没有任何影响。 如果有人能帮助我让Eclipse工作，我将不胜感激。 错误日志如下：

$ mv /.metadata/.plugins/org.eclipse.core.resources/.snap ~/temp/
要么
$ rm /.metadata/.plugins/org.eclipse.core.resources/.snap
使用Clean参数启动Eclipse。
eclipse.exe -clean
感谢Kninnug，我已经发现问题出现在我的工作区中，而不是日食。 我最终只是将所有内容导入新工作区。 谢谢大家的帮助。
我使用Eclipse Juno遇到了同样的问题，我将其用于Android开发。
作为Windows的解决方法，我从控制台启动它，如下所示：
C：\ path \ to \ eclipse \ eclipse -clean
要么
DELETE：/ [PATH TO WORKSPACE] /。metadata / .plugins / org.eclipse.core.resources
如果以上都不起作用，请阅读http://www.metod.si/job-found-still-running-after-platform-shutdown-eclipse/
问题在于您正在处理的工作空间/项目而不是eclipse。 一个解决方案是如果你使用maven就是清理和安装。
