使用阿里云的镜像库：http://maven.aliyun.com/nexus/content/groups/public/        具体配置如下

buildscript {

    repositories {
//        google()
//        jcenter()
        maven{url 'http://maven.aliyun.com/nexus/content/groups/public/'}
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.3'


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

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