 } else {

commandLine'/Users/zhoudezheng/Desktop/Android/tools/ndk-bundle/ndk-build','-C', file('src/main').absolutePath

    }

}

'/Users/zhoudezheng/Desktop/Android/tools/ndk-bundle/ndk-build' 由于不懂这个。导致我代码提示

------------------------------其实ndk-build是/Users/zhoudezheng/Desktop/Android/tools/ndk-bundle/目录下的一个文件。我以为是目录。导致我老是找不到这个路径---------------------------------------------------------
