Connect to maven.google.com:443

开发中经常遇到这个问题，由其是在最近google很多网站无法访问，打开一些工程时遇到Connect to maven.google.com:443 [maven.google.com/172.217.163.46] failed: connect timed out
解决思路就是换一个服务器，阿里云搭建了相同的maven仓库，替换一下地址就行了：
修改前

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
//      google()
        maven { url 'https://maven.google.com' }
                jcenter()
        
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'
    }
}

allprojects {
    repositories {
//      google()
        maven { url 'https://maven.google.com' }
        jcenter()
        maven { url 'http://raw.github.com/saki4510t/libcommon/master/repository/' }
    }
}

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

修改后

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
//      google()
//      maven { url 'https://maven.google.com' }
        jcenter()
        maven {
            url 'https://maven.aliyun.com/repository/google'
            name 'Google'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'
    }
}

allprojects {
    repositories {
//      google()
//      maven { url 'https://maven.google.com' }
        jcenter()
//      maven { url 'http://raw.github.com/saki4510t/libcommon/master/repository/' }
        maven {
            url 'https://maven.aliyun.com/repository/google'
            name 'Google'
        }
    }
}
