请尝试从任务栏结束任务Eclipse。这对我很管用。

当您没有正确关闭eclipse.exe时，就会发生这种情况。

*打开任务管理器->结束任务你的eclipse->现在打开eclipse.exe它将工作。

希望它能帮助到别人。

在我的例子中，在工作区的位置C:\之前有一个空格。我删除了那个空间，这就足够了:)

有时，如果你在Windows上，你可能看不到所有的进程——或者在任务管理器中看不到罪魁祸首进程。我必须点击“显示所有用户的进程”，我必须杀死这个java.exe，以便回到我的工作空间。

看起来你的工作空间是在Java TM中使用的，打开任务管理器并关闭eclipse.exe和Java TM进程。

下面是解决这个问题的几个步骤。4步对我来说很有用。

Delete .log files along .metadata folder. Check the current user permission make sure to check the full control checkbox click apply then OK. If you run system drive defragmentation or maintenance before you run eclipse editor sometimes original file path are not in their respective path to make sure run "previous version" time before your system maintenance of your drive where the eclipse workbench or something similar to this was saved. This last option is works for me. Check the drive letter of your current drive where the code editor was saved. If something unusual e.g before your maintenance your drive letter is K then after defragment or maintenance. The drive letter is now L hence you should change the drive letter to its original one that is K. to do this click the ff: Open control panel System & security Administrative tools Computer management Disk management in disk mngt choose the Drive example L then right click > change drive letter & path > click remove > then ok, open it again then > click add and > choose your original drive letter for that drive then click ok. If you use your computer for a long period of time do restart first to refresh everything.
