1、下载Gradle

官网：https://gradle.org/releases/

2、配置Gradle环境变量

3、更换镜像源

gradle安装目录下找到init.d文件夹

 再该文件夹中创建init.gradle文件，编写一下脚本替换阿里云镜像

// 阿里云仓库和源仓库地址对比：https://developer.aliyun.com/mvn/guide

gradle.projectsLoaded {
    rootProject.allprojects {
        buildscript {
            repositories {

                url CENTER_URL
            }
        }
    }
}

4、idea中更换gradle为本地安装
