Answer 1

尝试更改工作区，如果有效，请进行更改工作区提示。要强制更改工作区提示，请进行以下更改。

尝试更改工作区，如果这有效，请尝试更改工作区提示。要强制更改工作区提示，请执行以下更改。

<Eclipse_root_dir>\configuration\.settings\org.eclipse.ui.ide.prefs and set SHOW_WORKSPACE_SELECTION_DIALOG to true

1. 如果这个方法有效，前往 workspace\.metadata\.plugins\org.eclipse.core.resources 并删除 .snap 文件。

2. 如果第一种方法无效，请尝试删除 workspace\.metadata\.plugins\org.eclipse.core.resources 文件夹。请确保先备份以防将来需要。

你想尝试一下我刚刚在答案中编辑的#2吗？ - user1401472

Nr2 对我有效，但是我工作区中的所有项目都被删除了。 - LegionDev

Answer 2

经过约30-45分钟的尝试，我发现在%eclipse_workspace%.metadata.plugins\org.eclipse.core.resources.root中有一个扩展名为“.tree”的文件。我将其删除后，就可以重新启动Eclipse了。不过我的工作空间中所有的项目都被删除了。

Answer 3

尝试删除.metadata文件夹下plugins中创建的.snap文件夹。 例如，我的工作区位于位置 -> C：\ RawWorkspace \ .metadata将位于C：\ RawWorkspace.metadata

您可能需要从以下插件中删除.snap - C：\ RawWorkspace.metadata.plugins \ org.eclipse.core.resources

我在Resource插件中遇到了错误。因此，我从资源插件中删除了.snap。

Answer 4

我遇到了同样的问题，尝试了很多方法，但以下其中一种在我的情况下起作用：

1. 导航到WorkSpace.metadata.plugins\org.eclipse.core.resources.root
2. 删除*.tree文件

希望这对你有用 - 祝你好运。

- Muhammad Mudassar

Answer 5

当我遇到与原帖中提到的相同问题时，删除.snap文件对我有用。

打开workspace.metadata.plugins\org.eclipse.core.resources并删除.snap文件。

谢谢！

- Sumit Kumar

Answer 6

我曾经遇到过同样的问题，用户1401472的第一种解决方案对我有效。

从受损工作区恢复项目只需要通过以下步骤将它们从旧工作区重新导入到新工作区中：文件 -> 导入 -> 通用 -> “从现有工作区导入现有项目”，然后选择旧工作区文件夹作为根目录。

编辑：这是在Windows 10上进行的操作。
