Android Studio中添加阿里云Maven仓库镜像

     maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
     maven { url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }
     maven { url 'http://maven.aliyun.com/nexus/content/repositories/google' }
     maven { url 'http://maven.aliyun.com/nexus/content/repositories/gradle-plugin' }  

在项目的根build.gradle中添加如下：

buildscript {
    repositories {
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        maven { url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }
        maven { url 'http://maven.aliyun.com/nexus/content/repositories/google' }
        maven { url 'http://maven.aliyun.com/nexus/content/repositories/gradle-plugin' }
        google()
        jcenter()
        
    }
	...
}

allprojects {
    repositories {
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        maven { url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }
        maven { url 'http://maven.aliyun.com/nexus/content/repositories/google' }
        maven { url 'http://maven.aliyun.com/nexus/content/repositories/gradle-plugin' }
        google()
        jcenter()
       ...
    }
}

        maven { url 'https://maven.aliyun.com/repository/public' }
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }
        google()
