AndroidStudio: connect reset

一般是资源下载不下来问题，配置一下，使用阿里云服务器下载
配置build.gradle
主要是添加这三句

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

// 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/google' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }
//        google()
//        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.0.1'
        

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

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