本文主要记录gradle在大型项目中的配置。

工程目录下配置一个.gradle文件

如上图在工程目录下配置一个.gradle文件。用来存储所有用到的第三方sdk的名字和版本号。以后sdk升级只需要修改对应的版本号即可。
之前也配置过一种存储所有第三方sdk的名字和版本号的.gradle，但是感觉没有这个管理起来方便（这里就不贴出来了，需要的小伙伴可以留言）

ext.deps = deps

library.gradle用来存放各个moudule中重复定义的东西。其它moudule只需要引入该文件即可

apply from: rootProject.file('library.gradle')

dependencies {
    implementation deps.rxjava2.rxjava
}

ps:moudule下的xxx.iml文件一定不要删除，否则会引起一些莫名其妙的错误。
