!MESSAGE MyProject does not exist
当然，我尝试在eclipse上删除我的项目，然后再次将其导入，但是并不能解决问题.更糟糕的是，所有其他项目都具有相同的错误，即使该项目不再位于工作空间中，也要引用该项目.
Of course, I tried to delete my project on eclipse, then importing it again, but it did not solve the case. Even worse, all other projects have the same error, referring to that project, even if it is not in the workspace anymore.
您知道它的来源吗?
推荐答案
当我在命令行中执行git命令时，Eclipse进入了这种状态.(切换分支或进行更改.)我认为这是与Scala-IDE的某种互动.
Eclipse got into this state when I performed git commands in the command-line. (Switching branches or pulling changes.) I think it's some interaction with Scala-IDE.
通常，查找对话框不会出现.但是，如果确实出现，则Java面板将为空白，并且在尝试关闭此模式对话框时，将从事件循环内部触发异常，并且窗口拒绝关闭.
Usually the find dialog would just not appear. However if it did appear the Java panel would be blank, and when trying to close this modal dialog an exception fired from inside the event loop and the window refused to close.
对我来说决议是
- 重新创建错误消息中提到的丢失的项目.
- 再次尝试查找，阅读消息.(如果查找"对话框没有关闭，请杀死Eclipse.)
- 在第2步预期的位置创建一个空文件(例如
src/main/scala/com/example/MyFile.scala)
然后问题消失了，我可以再次删除虚拟项目.
Then the problem went away and I could delete the dummy project again.
