修改Project模式下的/build.gradle 换源

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript 
    repositories 
        maven  url 'https://plugins.gradle.org/m2/' 
        maven  url 'https://maven.aliyun.com/nexus/content/repositories/google' 
        maven  url 'https://maven.aliyun.com/nexus/content/groups/public' 
        maven  url 'https://maven.aliyun.com/nexus/content/repositories/jcenter'
//        google()
//        jcenter()
    
    dependencies 
        classpath 'com.android.tools.build:gradle:4.1.1'

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


allprojects 
    repositories 
        maven  url 'https://plugins.gradle.org/m2/' 
        maven  url 'https://maven.aliyun.com/nexus/content/repositories/google'

//        google()
//        jcenter()
    


task clean(type: Delete) 
    delete rootProject.buildDir

关掉AS再打开，飞起！

报错

Module: 'simpleDemo' platform 'android-30' not found.

解决办法：

修改\\simpleDemo\\build.gradle，从

compileSdkVersion 30

到

compileSdkVersion 33

保存，重启即可.

没有android33？ 点这看：

怎么下载更多的android版本？ 。。。。 没有爬墙的梯子，就别想了。。。。
