我有一个类似的崩溃，并开始日食与-clean选项没有帮助。 我最终删除了.metadata\.plugins\org.eclipse.e4.workbench文件，它解决了这个问题。
那就对了。 你可以通过在工作台目录中删除或重命名这个文件夹来解决这个问题 – .metadata / .plugins / org.eclipse.e4.workbench到.metadata / .plugins / org.eclipse.e4.workbench.temp 。
转到您的Workspace / .metadata / .plugins并删除所有内容。 Eclipse将启动并重新生成文件夹和文件。
对于windows用户，该文件夹位于工作区C:\Users\elminson\workspace\\.metadata\\.plugins
重要如果您将工程保存在工作区文件夹中，请立即备份
请参阅如何在清洁模式下运行eclipse？ 如果我们这样做会发生什么？

- 打开您的任务pipe理器 – >右键单击javaw.exe进程 – >select结束进程树（这将结束您的计算机上运行的所有Java运行时进程）。
然后去你的Eclipse文件夹 – > configuration.settings并删除org.eclipse.ui.ide.prefs文件。 重新启动Eclipse并尝试再次打开您的工作区。 这对我来说是诀窍:)要知道，删除这个文件会导致重新设置工作空间的历史logging，因此在启动Eclipse时需要手动浏览到工作空间的位置。
- 删除工作区文件夹或重命名它
我的机器很慢，我试图closures日食。 几次尝试后，日食结束。 在我重新启动机器后，日食没有被打开，它显示了多个错误。
我删除了.\metadata\.plugins\org.eclipse.jdt.ui\variablesAndContainers.data file and .\metadata\.plugins\org.eclipse.e4.workbench\workbench.xmi文件。
之后，日食是工作。
上述几点没有为我工作，我只是在任务pipe理器检查内存使用情况。 令我震惊的是，我发现，在我拥有的2GB内存中，我剩下了100MB。 Eclipse从那里拿了1 GB。 我杀了所有其他不需要的应用程序，然后重新运行eclipse。
它只是工作:-)
现在，当我运行eclipse时，我运行它没有任何不需要的 ， RAM消耗的应用程序
