Android-->build.gradle-->productFlavors

首先贴出官网:https://google.github.io/android-gradle-dsl/current/index.html

最外层的build.gradle是配置一些module共用的内容

// Top-level build file where you can add configuration options common to all sub-projects/modules.//构建脚本的配置buildscript {    //仓库    repositories {        jcenter()//        maven{//            url 'https://xxx/xxx'//        }    }    //依赖    dependencies {        classpath 'com.android.tools.build:gradle:2.3.3'        // NOTE: Do not place your application dependencies here; they belong        // in the individual module build.gradle files    }}//配置子模块的共用行为allprojects {    repositories {        jcenter()    }}//clear任务task clean(type: Delete) {    delete rootProject.buildDir}

settings.gradle是配置项目中引入了那几个模块，或者修改名称

//路径不能用/，只能用:include ':app', ':lib:library'//project(':app').buildFileName = 'abc.gradle'

gradle/wrapper/gradle-wrapper.properties

这个文件主要配置了我们要用的gradle的版本，如果新拷贝进来一个项目，本地没有对应的gradle的话，可以直接修改这个文件里的版本，就不用等待他下载了


本地路径在:C:\Users\Administrator.gradle\wrapper\dists,记的点击进去看看是否下载完成了
