android studio: 让项目通过阿里云 maven jcenter 下载依赖资源

打开项目根目录下的 build.gradle（Project:项目名称一级的gradle），如下所示添加阿里 maven 库地址：

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

buildscript {
    
    repositories {
        maven { url 'https://maven.aliyun.com/repository/public' }
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
        maven { url 'https://maven.aliyun.com/repository/central' }
        maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }
//        google()
//        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'

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

allprojects {
    repositories {
        maven { url 'https://maven.aliyun.com/repository/public' }
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
        maven { url 'https://maven.aliyun.com/repository/central' }
        maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }
//        google()
//        jcenter()
    }
}

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