GitHub - googlesamples/unity-jar-resolver: Unity plugin which resolves Android & iOS dependencies and performs version management

引入谷歌包时发现有这个玩意，主要用途是自动搜索工程内任意文件夹下的Editor/*Dependencies.xml文件

<dependencies><androidPackages><androidPackage spec="com.google.android.gms:play-services-ads:[22.3.0]"><repositories><repository>http://maven.aliyun.com/nexus/content/groups/public/</repository></repositories></androidPackage></androidPackages><iosPods><iosPod name="Google-Mobile-Ads-SDK" version="~> 10.9"><sources><source>https://github.com/CocoaPods/Specs</source></sources></iosPod></iosPods>
</dependencies>

例如上方的<androidPackages>下的每一个<androidPackage>都是一个依赖项implementation
<repositories>指定包来源url 我指定的是镜像url 

<iosPods>是iOS的也同理，最终会输出到mainTemplate.gradle(前提是你已经勾选了Custom Main Template)选项。
