Android Studio 报 Caused by: org.gradle.api.internal.artifacts.ivyservice.DefaultLenientConfig 的错误

1、查看是不是把Gradle的离线模式给打开了（若打开了，请把离线模式关闭）

2、添加可访问到的仓库

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

buildscript {
    
    repositories {
        google()
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/'}
        maven { url'https://maven.aliyun.com/repository/public/' }
        maven { url'https://maven.aliyun.com/repository/google/' }
        maven { url'https://maven.aliyun.com/repository/jcenter/' }
        maven { url'https://maven.aliyun.com/repository/central/' }
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0'
        

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

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

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