Eclipse编辑器将不会打开 [英] Eclipse editor won't open

问题描述

错误：

无法打开编辑器：编辑器类无法实例化。
这通常表示缺少的无参数构造函数或
编辑器的类名在plugin.xml中输入错误。

Could not open the editor: The editor class could not be instantiated. This usually indicates a missing no-arg constructor or that the editor's class name was mistyped in plugin.xml.

注意：

• 我正在为C ++使用不同的Eclipse（而不是插件） Python - 它们完美无缺，只是引起麻烦的java eclipse。


• 我已经尝试重新安装eclipse，甚至重新安装java。任何想法？


• 它没有显示项目文件的麻烦，它是只是* .java和* .class文件无法打开。

编辑2：

我更改了工作区，它修复了问题（至少为新的工作区），但仍然 - 不知道为什么会发生。 （虽然我仍然好奇，所以我打开这个问题）。

EDIT 2:
I changed the workspace and it fixed the problem (for the new workspace at least) but still - no idea why it happened. (though I am still curious, so I leave this question open).

推荐答案

这通常是由eclipse插件。
检查YOUR_WORKSPACE / .metadata / .plugins / org.eclipse.jdt.core /
有很多索引文件。有时它有助于删除它们。
还可以用-clean启动你的eclipse。

This is often a problem with temporary files saved by eclipse plugins. Check YOUR_WORKSPACE/.metadata/.plugins/org.eclipse.jdt.core/ There are a lot of index files. Sometimes it helps to delete them. Also start your eclipse with -clean.

但是我认为你的问题略有不同。
您是否在文件系统的某个位置引用了库（jar文件）？
如果你删除它或移动它，eclipse无法构建你的项目。

But i think your problem is slightly different. Did you have a reference to a library(jar-file) somewhere in your filesystem? If you deleted it or moved it, eclipse can't build your projects.

你刷新了所有的项目？

最好的问候Florian
