cocos2d-x打包的时候出现空指针的问题，An error has occurred.

最近在用cocos2dx 3.x版本做android版本的时候，出现点击工程-属性-C/C++ builder的时候会提示

The currently displayed paye contains invalid values

或者

An error has occurred. See error log for more details.

java.lang.NullPointerException

解决办法是打开proj.android下面的 ".cproject"文件，可以看到里面是这里内容：

然后把里面的这一部分代码删除，删除包含org.eclipse.cdt.managedbuilder.core.configurationDataProvider的cconfiguration块：

<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">

</extensions>
</storageModule>
<storageModule moduleId="org.eclipse.cdt.core.externalSettings"/>
</cconfiguration>

保存后即可，原因未知，我在eclipse中新建android工程时没有问题的，

但是倒入cocos2dx打包的时候就有这个问题，我也不知道什么情况，有知道的欢迎回复

一下，特此记录一下，非常感谢这位作者的参考，才解决了一直困扰我的问题。
