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
