在linux中使用gradle命令行构建程序时，使用国内镜像可以大大加快我们的构建过程，节约我们的时间，下面就如何配置aliyun仓库作为gradle的默认仓库作出说明。

1. 如果只想对单个项目生效，那么可以在项目的build.gradle中添加如下配置：

   buildscript {
       repositories {
           maven {url 'https://maven.aliyun.com/repository/google/'}
           maven {url 'https://maven.aliyun.com/repository/jcenter/'}
       }
       dependencies {
           classpath: 'com.android.tools.build:gradle:2.2.3'
   
       }
   }
   allprojects {
       repositories {
            maven { url 'https://maven.aliyun.com/repository/google/' }
            maven { url 'https://maven.aliyun.com/repository/jcenter/'} 
       }
   }

2. 如果是对所有项目生效，那么需要在用户的家目录下面的.gradle目录下创建init.gradle文件，内容如下：

   allprojects{
       repositories {
           def ALIYUN_REPOSITORY_URL = 'https://maven.aliyun.com/repository/public/'
           def ALIYUN_JCENTER_URL = 'https://maven.aliyun.com/repository/jcenter/'
           def ALIYUN_GOOGLE_URL = 'https://maven.aliyun.com/repository/google/'
           def ALIYUN_GRADLE_PLUGIN_URL = 'https://maven.aliyun.com/repository/gradle-plugin/'
           all { ArtifactRepository repo ->
               if(repo instanceof MavenArtifactRepository){
                   def url = repo.url.toString()
                   if (url.startsWith('https://repo1.maven.org/maven2/')) {
                       project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_REPOSITORY_URL."
                       remove repo
                   }
                   if (url.startsWith('https://jcenter.bintray.com/')) {
                       project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_JCENTER_URL."
                       remove repo
                   }
                   if (url.startsWith('https://dl.google.com/dl/android/maven2/')) {
                       project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_GOOGLE_URL."
                       remove repo
                   }
                   if (url.startsWith('https://plugins.gradle.org/m2/')) {
                       project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_GRADLE_PLUGIN_URL."
                       remove repo
                   }
               }
           }
           maven { url ALIYUN_REPOSITORY_URL }
           maven { url ALIYUN_JCENTER_URL }
           maven { url ALIYUN_GOOGLE_URL }
           maven { url ALIYUN_GRADLE_PLUGIN_URL }
       }
   }
