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

Question

当我使用“帮助 - ＆gt;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？我什么都没做，我只是从他们自己的“检查更新”中更新Eclipse。

Answer 1

正如您所看到的here，您的问题的解决方法就是将“〜/ .eclipse”移动到另一个文件夹。

<强>所以：

1. 关闭Eclipse
2. 打开“终端”
3. 键入以下命令：

e.g：

mv ~/.eclipse somewhereYouWant

当我遇到这个问题时，我只是：

mv ~/.eclipse home/paladini/Downloads

Answer 2

删除Eclipse Typescript plugin

时出现类似错误

试图打开typescript（*。ts）文件并收到此错误：

No editor descriptor for id com.palantir.typescript.text.typeScriptEditor

我不允许移动工作区。

关于Eclipse Oxygen，Window - ＆gt;透视 - ＆gt;关闭一切都为我工作。

Answer 3

要解决此问题，请将编辑器重置为默认配置： 在Eclipse（或STS ...）菜单栏中，进入：

Windows > Preferences > Editors >: Restore Defaults ; Apply and Close

顺便说一句，

Answer 4

在Windows中。

1. 打开Eclipse文件夹
2. 复制其中的所有文件和文件夹
3. 将其粘贴到其他位置
4. 从新位置启动Eclipse
5. 更改工作区位置
6. 开始。

Answer 5

这里的其他解决方案对我不起作用。

也许我的问题是由于尝试第一次进行eclipse设置并重新安装了它的不同版本而导致的：c ++版本，然后是普通基础版本+单独安装的附件。 （因为我也想将其用于其他语言，所以我对如何设置它感到困惑。）

解决方案：：我关闭了Eclipse，然后重命名为：~/eclipse，~/workbench和~/.eclipse； （换句话说，将其删除），最后重新安装并重新启动。

cd ~
mv .eclipse           .eclipse~            #renames
mv  eclipse            eclipse~ 
mv  eclipse-workspace  eclipse-workspace~

~/nobak/Installers/eclipse/eclipse-installer/eclipse-inst    #reinstall

eclipse/cpp-2018-09/eclipse/eclipse   #restart
