gradle 下载太慢，一直在gradle build running

问题

初次打开项目，gradle等第三方下载很久、编译很久、跑项目很久

解决：设置国内代理

原因：资源在国外，下载太慢
将build.gradle设置成阿里云代理，去阿里云下载

buildscript {
    repositories {
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/central' }
        maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }
        google()
        maven {url 'https://developer.huawei.com/repo/'}
    }
    }
    
    ...

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