无法在Eclipse中打开工作区

Question

我在使用Eclipse Kepler过程中遇到了崩溃问题。

现在我无法在请求的工作区打开Eclipse（在其他工作区可以正常打开）。

选择工作区后，会弹出一个消息框：

发生错误，请查看日志文件。...WORKSPACE/.metadata/.log

打开日志文件：

• 我尝试重新启动电脑两次（确保没有文件被锁定）。
• 我尝试删除服务器文件夹。

我的最新工作未提交到SVN。

有任何建议吗？

谢谢，

- Mike

Answer 1

找到解决方案了！

我删除了文件：/.metadata/.plugins/org.eclipse.core.resources/.snap，问题得到解决。

谢谢！

- Mike

太好了，成功了。我不得不删除.snap和36.snap，然后它就可以工作了。 - 2sb

Answer 2

删除.metadata\.plugins\org.eclipse.core.resources目录下的.snap文件后，程序可以正常运行。

Answer 3

我认为这是一个错误，你无法解决它。 尝试将工作区中的所有工作移动到新的工作区，因为这与捆绑包有关，这就是之前崩溃的原因，并且它不会在同一工作区上运行。

- Anatch

Answer 4

删除你的工作区。然后打开 Eclipse。 在删除之前备份。

谢谢，我没有意识到从头开始会帮助他解决问题，但不确定这样做如何解决问题，他无法启动Eclipse并在之前的上下文中工作，这就像说如果你的车坏了，就把它扔掉，买一辆新车，这是一个奇怪的解决问题的方式。 - tonio

Answer 5

我正在运行Red Hat Jboss Developer Studio 10.0（Eclipse的捆绑版本），并遇到了同样的问题。 在C:\workspace.metadata.plugins\org.eclipse.core.resources中删除*.snap文件对我有用。（这是在一个意外的重启后，我无法确认最后一个Eclipse关闭弹出窗口。） 至于为什么删除它会起作用，根据What are *.snap files in eclipse?所述： “*.snap文件代表IDE在运行时工作区状态的更改。这主要是为了eclipse崩溃恢复计划。当发生崩溃时，这些文件用于恢复eclipse工作区的状态。” 显然，如果崩溃足够严重，则快照文件将损坏，并且无法返回到最后一个良好的状态。但是，让Eclipse正常运行总比没有好。您可能需要重新导入您的项目（我不得不导入我的最新项目）。
