android Gradle:Download 很慢, 有时候要等很久：

我们可以配置国内镜像来解决：

直接修改 工程的 build.gradle 文件

buildscript {
    ext.kotlin_version = '1.7.10'
    repositories {
        google { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/public' }
        mavenCentral()
        jcenter { url 'https://maven.aliyun.com/repository/public' }
    }

    dependencies {
        //classpath 'com.android.tools.build:gradle:7.2.0'
        classpath 'com.android.tools.build:gradle:4.2.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        google { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/public' }
        mavenCentral()
        jcenter { url 'https://maven.aliyun.com/repository/public' }
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

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

速度就可以起飞了！！
