android-studio 阿里云镜像加速

背景
平时安卓项目编译较慢，其中一个原因就是要下载依赖资源包比较慢。为了解决这个问题，可以配置阿里云镜像，加速下载。

配置方法
对特定项目生效，修改项目根目录下的build.gradle文件内容
增加如下信息:

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

buildscript {
    repositories {
        maven { url 'https://maven.aliyun.com/nexus/content/groups/public/' }
        maven { url 'https://maven.aliyun.com/nexus/content/repositories/jcenter' }
        maven { url 'https://maven.aliyun.com/nexus/content/repositories/google' }
        maven { url 'https://maven.aliyun.com/nexus/content/repositories/gradle-plugin' }
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
    }
}

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