解决gradle 在 Android studio配置失败的方法

首先更换镜像源
更换可用的镜像源
// 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/nexus/content/repositories/jcenter’ }
maven { url ‘http://maven.aliyun.com/nexus/content/repositories/google’ }
maven { url ‘http://maven.aliyun.com/nexus/content/repositories/gradle-plugin’ }
mavenCentral()
maven { url “https://jitpack.io” }
maven { url ‘https://dl.google.com/dl/android/maven2/’ }
google()

}
dependencies {
    classpath 'com.android.tools.build:gradle:3.5.3'
    
    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}

}

allprojects {
repositories {
maven { url ‘http://repol.maven.org/maven2’ }
maven { url ‘http://maven.aliyun.com/nexus/content/groups/public/’ }
maven { url ‘http://maven.aliyun.com/nexus/content/repositories/jcenter’ }
maven { url ‘http://maven.aliyun.com/nexus/content/repositories/google’ }
maven { url ‘http://maven.aliyun.com/nexus/content/repositories/gradle-plugin’ }
mavenCentral()
maven { url “https://jitpack.io” }
maven { url ‘https://dl.google.com/dl/android/maven2/’ }
google()

    jcenter()


}

}

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

如果更换之后然后 下载不了 建议开热点
最好是联通热点
