项目构建gradle在这里 .

buildscript { 
    repositories {
        google()
        mavenCentral()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0'
        classpath 'com.google.gms:google-services:3.2.0'
      }
    }

     allprojects {
    repositories {
        google()
        jcenter()

       }
     }

     task clean(type: Delete) {
        delete rootProject.buildDir
     }
}

App build gradle
