由于新版AS将allprojects独立出来变为setting.gradle, 所以我们只需要更改setting.gradle即可:

将以下对应阿里云镜像添加到google和mavenCentral上方，优先从国内源下载，如果没有再去原网站下。

maven { url 'https://maven.aliyun.com/repository/google' }maven { url 'https://maven.aliyun.com/repository/public' }
pluginManagement {repositories {gradlePluginPortal()maven { url 'https://maven.aliyun.com/repository/google' }maven { url 'https://maven.aliyun.com/repository/public' }google()mavenCentral()//jcenter()}}dependencyResolutionManagement {repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)repositories {maven { url 'https://maven.aliyun.com/repository/google' }maven { url 'https://maven.aliyun.com/repository/public' }google()mavenCentral()}}
