AndroidStudio新建项目报错

Unable to resolve dependency for ':app@debugAndroidTest/compileClasspath': Could not resolve com.google.android.gms:play-services-maps:11.8.0

project目录下build.gradle添加以下代码： 

allprojects {

    repositories {

        google()

        jcenter()

        maven { url "https://maven.google.com" }

    }

}

如果用到google_service.json

apply plugin: 'com.google.gms.google-services'

classpath后面添加：classpath 'com.google.gms:google-services:3.2.0'

然后再 sync，接下来就等待。。。
