参考地址：https://developer.aliyun.com/mvn/guide

buildscript {
    repositories {
// 添加阿里云 maven 地址
        maven { url 'https://maven.aliyun.com/repository/gradle-plugin/' }
        maven { url 'https://maven.aliyun.com/repository/central/' }
        maven { url 'https://maven.aliyun.com/repository/public/' }
        maven { url 'https://maven.aliyun.com/repository/google/' }
        google()
        jcenter()
    }
}
 
allprojects {
    repositories {
// 添加阿里云 maven 地址
        maven { url 'https://maven.aliyun.com/repository/gradle-plugin/' }
        maven { url 'https://maven.aliyun.com/repository/central/' }
        maven { url 'https://maven.aliyun.com/repository/public/' }
        maven { url 'https://maven.aliyun.com/repository/google/' }
        google()
        jcenter()
    }
