修正android cocos2dx项目当点击属性时提示错误的问题

近期在用cocos2dx 3.x版本号做android版本号的时候，出现点击project-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

解决的方法是打开proj.android以下的 ".cproject"文件

删除包括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">
				<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>

保存后就可以，原因未知。有知道的能够回复一下~

特此记录，困扰一晚上的问题。
