使用NullpointerException运行的分级调试崩溃很好

Question

当尝试在Android中调试我的应用程序时，Gradle会与NullpointerException崩溃。只运行这个应用程序就行了。Android 2.3.3。

下面是gradle堆栈跟踪：

java.lang.NullPointerException

这是我在应用程序文件夹中的build.gradle。更多细节:这是一个带有Cocos2d-x游戏引擎的项目，我正在尝试让调试使本机代码正常工作。一个简单的测试项目确实有效，但我自己的项目不起作用。

编辑:我已经按以下顺序尝试过了：

1. 重建工程
2. 清洁工程
3. 使缓存失效/重新启动
4. 万一你在使用Gradle deamon。让它停止。/梯度--停止，从1到3开始。
5. 最后&完全关闭Android，并从项目的根目录中隐藏delete .gradle directory，然后再次启动Android。
6. 关闭所有其他Android实例
7. 重启OSX

确保在项目结构上正确配置了NDK路径(File > Project > SDK Location > Android位置)。单击“确定”并再次尝试同步。
