Cannot get property 'compileSdkVersion' on extra properties extension as it does not exist问题解决

情景:当在 导入 外项目的 lib 库中遇到了 这个问题,

原因: 

这个问题表示 项目中的多个项目的 compileSdkVersion 都不一致.

解决办法: 

如果有很多项目，可以设置全局来统一管理版本号或依赖库，

根目录下build.gradle下： 

ext { 

compileSdkVersion = 23 

buildToolsVersion = “23.0.2” 

minSdkVersion = 14 

targetSdkVersion = 23 

}



报Cannot get property ‘compileSdkVersion’ on extra properties extension as it does not exist ,加compileSdkVersion

报Cannot get property ‘buildToolsVersion’ on extra properties extension as it does not exist ,加buildToolsVersion

就这么简单 :-D
