Android Studio使用阿里云镜像

更换项目级别中的build.gradle中的配置

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

buildscript { 
    ext.kotlin_version = '1.3.20'

    
    repositories {
        maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        google()
        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
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" }
}

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

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

要点：放在gogole和jenter上面。他会从上往下找。
