google-services插件发生了什么？

Question

google-services插件当前在我的项目中无法解析。我收到错误消息：

 What went wrong: A problem occurred configuring root project ''.
> Could not resolve all files for configuration ':classpath'.
   > Could not find com.google.gms:google-services:4.0.2.

当我在此处浏览Google Maven存储库时：https://dl.google.com/dl/android/maven2/index.html

只是缺少google-services库。
