java - Eclipse启动时出现错误: 'Android LIbrary Update' has encountered

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，会出现一个对话框，其中显示:

`Android Library Update` has encountered a problem.

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

点击对话框上的详细信息按钮会产生:

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

任何帮助或建议将不胜感激。感谢您的宝贵时间:)

编辑 1: 我的问题现在已经解决了。我最终尝试了另一个 SDK，但问题仍然存在。我最终变得不耐烦，创建了一个新项目并重新导入了我的源代码。这让我相信我的问题可能部分是由于 .cproject 和/或 .project 文件损坏造成的。

这可能是一个 super 主观的事情，因为错误是如此普遍，但最好的做法是检查您的 .cproject。

我有我的.cproject检查版本控制，我注意到它包含以下添加内容:

<cconfiguration id="0.1230402123.1377291156"> <storageModule buildSystemId="org.eclipse.cdt.managedbuilder.core.configurationDataProvider" id="0.1230402123.1377291156" moduleId="org.eclipse.cdt.core.settings" name="Debug"> <externalSettings/> <extensions> <extension id="org.eclipse.cdt.core.VCErrorParser" point="org.eclipse.cdt.core.ErrorParser"/> <extension id="org.eclipse.cdt.core.GmakeErrorParser" point="org.eclipse.cdt.core.ErrorParser"/> <extension id="org.eclipse.cdt.core.CWDLocator" point="org.eclipse.cdt.core.ErrorParser"/> <extension id="org.eclipse.cdt.core.GCCErrorParser" point="org.eclipse.cdt.core.ErrorParser"/> <extension id="org.eclipse.cdt.core.GASErrorParser" point="org.eclipse.cdt.core.ErrorParser"/> <extension id="org.eclipse.cdt.core.GLDErrorParser" point="org.eclipse.cdt.core.ErrorParser"/> </extensions> </storageModule> <storageModule moduleId="org.eclipse.cdt.core.externalSettings"/> </cconfiguration>

一旦我关闭 Eclipse，删除它们，然后重新启动，错误就消失了。 重新创建一个项目也会做同样的事情，但我不想重做我精心设置的项目。希望这会有所帮助。
