android阿里云镜像

gradle同步特别慢，网上收集的几种方法。

android/build.gradle

repositories {
       maven { url \'https://maven.aliyun.com/repository/jcenter\' } 
       maven { url \'https://maven.aliyun.com/repository/google\' } 
       jcenter() 
       google() 
}

第二个比较完整，推荐

buildscript {
    ext.kotlin_version = \'1.2.71\'
    repositories {
    	// 以下四行代码为阿里gradle 源
        maven{ url \'https://maven.aliyun.com/repository/google\'}
        maven{ url \'https://maven.aliyun.com/repository/gradle-plugin\'}
        maven{ url \'https://maven.aliyun.com/repository/public\'}
        maven{ url \'https://maven.aliyun.com/repository/jcenter\'}
        google()
        jcenter()
    }
    dependencies {
        classpath \'com.android.tools.build:gradle:3.2.0\'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
    	// 所有的model 都优先使用阿里源
        maven{ url \'https://maven.aliyun.com/repository/google\'}
        maven{ url \'https://maven.aliyun.com/repository/gradle-plugin\'}
        maven{ url \'https://maven.aliyun.com/repository/public\'}
        maven{ url \'https://maven.aliyun.com/repository/jcenter\'}
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
