Question

Eclipse似乎在启动时给我一个错误，我不确定原因是什么。 eclipse启动后会立即显示一个对话框：

`Android Library Update` has encountered a problem.

An internal error occurred during:"Android Library Update".

点击对话框中的详细信息按钮会产生：

An internal error occurred during: "Android Library Update".
java.lang.NullPointerException

我的开发环境：
Ubuntu 14.04 LTS
Eclipse Luna Release (4.4.0)
Android Developer Tools 23.0.0.1245622
Android SDK r22.6.2
Android NDK r9d

此会话的工作区中的Eclipse .log包含：
