当我使用“帮助 -> 检查更新”更新 Eclipse 时，我遇到了问题。

如果我尝试启动 Eclipse，Eclipse 会打开但会显示如下错误消息:

  Could not open the editor: No editor descriptor 
  for id org.eclipse.jdt.ui.CompilationUnitEditor

在错误的“详细信息”中，我有以下描述:

我该怎么做才能解决这个问题？我什么都不做，我只是从他们自己的“检查更新”中更新 Eclipse。

最佳答案

如你所见here ，您的问题的解决方法是将“~/.eclipse”移动到另一个文件夹。

所以:

1. 关闭 Eclipse
2. 打开“终端”
3. 输入以下命令:

例如:

mv ~/.eclipse somewhereYouWant

当我遇到这个问题时，我只是:

mv ~/.eclipse home/paladini/Downloads
