I found the same bug in Eclipse once.
我曾经在 Eclipse 中发现了同样的错误。
This happened to me after a Windows Update.
这是在 Windows 更新后发生在我身上的。
What I did to resolve the problem was giving (again) "Full Control"/"Admin Write Read" permissions to Eclipse Folder, in my case was in "C:\eclipse-jee-kepler-SR2-win32-x86_64". (Right Click on it, then Properties -> Security Tab and Edit there at -least your user- with Full Control)
我为解决这个问题所做的是（再次）授予 Eclipse 文件夹“完全控制”/“管理员写入读取”权限，在我的情况下是在“C:\eclipse-jee-kepler-SR2-win32-x86_64”中。（右键单击它，然后属性 -> 安全选项卡并在那里编辑 - 至少你的用户 - 完全控制）
For some reason the Windows Update changed that.
出于某种原因，Windows 更新改变了这一点。

In my case, I had to switch ownership back to my ID in my workspace/.metadata folder, then all was well. I had inherited an old user ID for my login after a system update. [Ubuntu 14 --> 16]
就我而言，我必须将所有权切换回我的工作区/.metadata 文件夹中的 ID，然后一切正常。系统更新后，我为我的登录继承了旧用户 ID。[Ubuntu 14 --> 16]

I got this error in eclipse photon. I started photon with older workspace. I removed .metadata and .recommenders folders and then restarted the eclipse. It worked fine.
我在日食光子中遇到了这个错误。我从旧的工作区开始光子。我删除了 .metadata 和 .recommenders 文件夹，然后重新启动了 eclipse。它工作得很好。
