gradle__2">1 Android项目的build.gradle 文件

• 原文件：

buildscript {
    repositories {
        mavenCentral()
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.2'
    }
}
 
allprojects {
    repositories {
        mavenCentral()
        google()
        jcenter()
    }
}

2 修改镜像

• 刚创建工程时，下载某些组件，由于时国外的地址，网络下载收到限制，修改为国内的阿里云地址

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        maven {
            url 'http://maven.aliyun.com/nexus/content/groups/public/'
        }
        maven {
            url 'http://maven.aliyun.com/repository/google'
        }
        maven {
            url 'http://maven.aliyun.com/repository/jcenter'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.2'
    }
}

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

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