前言

太久没有搞过android app，今天更新Android Studio到 3.6.3版本，git clone一个网上项目，直接出现

解决思路

在build.gradle文件中加入 阿里云Maven仓库镜像。

// Top-level build file where you can add configuration options common to all sub-projects/modules.
apply from: "config.gradle"
buildscript {
    repositories {
        google()
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/'}
        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/' }
        jcenter()
    }
    dependencies {
        classpath 'com.google.gms:google-services:4.0.1'
        classpath 'com.android.tools.build:gradle:3.3.2'
//        classpath 'com.github.dcendents:android-maven-gradle-plugin:1.3'
//        classpath 'com.github.dcendents:android-maven-gradle-plugin:1.5'
//        classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.7.3'

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

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

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

以下代码即可解决gradle构建问题。
