  <p>How can I solve this?  </p>
  
  <p>Here my Project build gradle:</p>
  
  <pre><code>buildscript {
  
      repositories {
          google()
          jcenter()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:3.2.0'
  
  
          // NOTE: Do not place your application dependencies here; they belong
          // in the individual module build.gradle files
          classpath 'com.google.gms:google-services:4.0.2'
      }
  }
  
  allprojects {
      repositories {
          google()
          jcenter()
  
          maven { url 'https://jitpack.io' }
      }
  }
  
  task clean(type: Delete) {
      delete rootProject.buildDir
