在android开发中，因为各种原因，时常编译速度缓慢甚至卡住不动，切换到阿里云maven仓库之后，则可以提升编译速度。

google

https://maven.aliyun.com/repository/google

jcenter

https://maven.aliyun.com/repository/public

public（central仓和jcenter仓的聚合仓）

https://maven.aliyun.com/repository/public

gradle-plugin

https://maven.aliyun.com/repository/gradle-plugin

jcenter和public二选一即可。

build.gradle

buildscript {
    
    
   
    repositories {
    
    
        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' }
        mavenLocal()
        mavenCentral()

        google()
        jcenter()
        ...
    }
}

allprojects {
    
    
    repositories {
    
    
        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' }
        mavenLocal()
        mavenCentral()

        google()
        jcenter()
        ...
    }
}
