2，最初的build.gradle的配置

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

buildscript {
    
    repositories {
        mavenCentral()
        google()
        jcenter()
//        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
//        maven{ url 'http://maven.aliyun.com/nexus/content/repositories/jcenter'}
//        google()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
        

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

allprojects {
    repositories {
        mavenCentral()
        google()
        jcenter()
        maven { url 'https://maven.google.com'}
        mavenLocal()
//        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
//        maven{ url 'http://maven.aliyun.com/nexus/content/repositories/jcenter'}
//        google()
    }
}

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

 

3，将google的仓库替换为aliyun的仓库

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

buildscript {
    
    repositories {
//        mavenCentral()
//        google()
//        jcenter()
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        maven{ url 'http://maven.aliyun.com/nexus/content/repositories/jcenter'}

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
        

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

allprojects {
    repositories {
//        mavenCentral()
//        google()
//        jcenter()
//        maven { url 'https://maven.google.com'}
//        mavenLocal()
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        maven{ url 'http://maven.aliyun.com/nexus/content/repositories/jcenter'}
    }
}

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

4,用aliyun仓库替代后：

5，选择Add Google Maven repository and sync project 后 syn，编译成功了。
