body: <p>I am getting the following error :</p>
  
  <p>Could not find method maven() for arguments [build_3sdtqstdmsgdnexrxaaxgljji$_run_closure1$_closure4@325a800c] on root project 'Appointments' of type org.gradle.api.Project.</p>
  
  <p>Here's my Project Level Gradle File:</p>
  
  <pre><code>buildscript {
  
  repositories {
      google()
      jcenter()
      maven { url "http://jcenter.bintray.com"}

  }
  dependencies {

      classpath 'com.google.gms:google-services:4.0.0'
      classpath 'io.fabric.tools:gradle:1.25.4'
  
  
      // NOTE: Do not place your application dependencies here; they belong
      // in the individual module build.gradle files
  }
  }
  
  allprojects {
  repositories {
      google()
      jcenter()
  }
  maven {
      url 'https://maven.google.com/'
