Eclipse：无法打开编辑器：没有id的编辑器描述符org.eclipse.jdt.ui.CompilationUnitEditor

Question

当我使用“帮助 - >检查更新”更新Eclipse时，出现问题。

如果我尝试启动Eclipse，Eclipse的打开，但显示出这样的错误消息：

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

和错误的内“详细资料”，我有如下描述：

我能做些什么来解决这个问题？我什么也没做，我只是从他们自己的“检查更新”中更新Eclipse。

Answer 1

正如你所见，here，你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. 键入以下命令：

例如为：

mv ~/.eclipse somewhereYouWant 

当我这个问题，我只是：

mv ~/.eclipse home/paladini/Downloads 

Answer 2

在Windows中。

1. 打开Eclipse文件夹
2. 复制所有文件和文件夹，在其中
3. 它从新位置
4. 更改工作区位置
5. 开始粘贴到其他位置
6. 启动Eclipse。
