I had the same problem. Deleting .metadata/.plugins/org.eclipse.e4.workbench/workbench.xmiworked. I am not sure of the root cause, though.
我有同样的问题。删除.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi工作。不过，我不确定根本原因。
OR
或者
Move the contents of "plugins"folder to some other folder and restart eclipse. Eclipse will add all these plugins after restart. Replace the new folders with the copied folders.
将“plugins”文件夹的内容移动到其他文件夹并重新启动eclipse。Eclipse 会在重启后添加所有这些插件。用复制的文件夹替换新文件夹。

Removing the .snap file worked for me:
删除 .snap 文件对我有用：
rm WORKSPACE/.metadata/.plugins/org.eclipse.core.resources/.snap
rm WORKSPACE/.metadata/.plugins/org.eclipse.core.resources/.snap

"It seems to fail when trying to restore the workspace.
“尝试恢复工作区时似乎失败了。
Try:
尝试：
Open a new workspace. If it has been set to use a default, go to \configuration.settings\org.eclipse.ui.ide.prefs and set SHOW_WORKSPACE_SELECTION_DIALOG to true
打开一个新的工作区。如果已设置为使用默认值，请转到 \configuration.settings\org.eclipse.ui.ide.prefs 并将 SHOW_WORKSPACE_SELECTION_DIALOG 设置为 true
Try deleting /.metadata/.plugins/org.eclipse.core.resources/.snap
尝试删除 /.metadata/.plugins/org.eclipse.core.resources/.snap
As suggested in a comment: If using Eclipse 4, you may have to delete the file .metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi aswell."
正如评论中所建议的：如果使用 Eclipse 4，您可能还必须删除文件 .metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi。”
