[移动开发]as 配置离线环境

1. as 随便新建一个工程，修改gradle 中的库为阿里最新库，进行同步。 此时会下载最新的gradle 文件。?

2. 下载as 离线maven 包，对应解压。 注意解压目录?C:\Users\Administrator\.android\manual-offline-m2\gmaven_stable\android

3. 按照离线包的readme 中的描述 新建 init.d 中的配置文件， 注意配置文件本身不做修改。 同时增加gradle 中的全局属性gradle.properties 文件?user.home=C:\\Users\\Administrator

4? 再次编译，会某包未找到，用everything 查找，可以看出其在gradle 目录下， 而不在android 目录下。 使用 copy 工具对gradle 目录下的文件进行处理后，拷贝到android 目录。?

5. 如果还出现编译某包不存在的情况， 而缺少该包没有同步过来，基本上可以定位是网络问题， 无法下载相关的库 。?

copy 工具：?
