android studio 离线配置 gradle和依赖

配置本地gradle

gradle下载地址

修改gradle/gradle-wrapper.properties 文件的 distributionUrl

//本地文件存储路径
distributionUrl=file:///D:/gradle/gradle-6.7.1-all.zip
找到缓存的依赖：C:\Users\Administrator\.gradle\caches\modules-2\files-2.1

复制到一个空文件夹下：然后把下面代码复制到IDEA或者Eclipse中修改 path 和lastName；

开始执行

修改根目录的build.gradle

注释掉 google()、jcenter()、mavenCentral()...等 maven仓库

修改为本地仓库

repositories {
//这是本地文件路径
       maven {
          url 'D:\\maven\files-2.1'
      }
}

注意：

离线环境在与 DataBinding 使用过程中会报错，目前还没有解决
