Gradle使用国内源（阿里云源）

Gradle在国内经常抽风，一直使用梯子来使用倒是没有出现什么问题，今天梯子被墙了，Gradle就用不了。最近好像查的有点严，估计梯子一时好不了，试试换gradle国内源。没有想到换了国内源比用梯子更快，故特在此记录一下。

关闭Gradle的代理（如果没有设置代理跳过这一步）：

打开文件C:\Users\Administrator.gradle\gradle.properties，注释设置代理的行。

# When configured, Gradle will run in incubating parallel mode.

更换Gradle国内源

打开项目根目录的gradle.properties，注释所有google()和jcenter()的行，添加阿里云的源：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    
    repositories {
       // google()
       // jcenter()
        maven { url 'https://plugins.gradle.org/m2/' }
        maven { url 'https://maven.aliyun.com/nexus/content/repositories/google' }
        maven { url 'https://maven.aliyun.com/nexus/content/groups/public' }
        maven { url 'https://maven.aliyun.com/nexus/content/repositories/jcenter'}
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0'
        

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
      //  google()
      //  jcenter()
        maven { url 'https://plugins.gradle.org/m2/' }
        maven { url 'https://maven.aliyun.com/nexus/content/repositories/google' }
        maven { url 'https://maven.aliyun.com/nexus/content/groups/public' }
        maven { url 'https://maven.aliyun.com/nexus/content/repositories/jcenter'}
    }
}

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