title: Android Studio- Program type already present: com.google.android.gms.internal.measurement.zzwp
body: <p>Yesterday,my app was working fine.</p>
  
  <p>Today, I don't know why, the app didn't compile anymore after I reopened the Android Studio.</p>
  
  <p>The error shown is </p>
  
  <pre><code>Program type already present: com.google.android.gms.internal.measurement.zzwp
  Message{kind=ERROR, text=Program type already present: com.google.android.gms.internal.measurement.zzwp, sources=[Unknown source file], tool name=Optional.of(D8)}
  </code></pre>
  
  <p>I really don't know what's going on, I've searched everything and nothing worked.
  If someone could help me, I would really appreciate.
  I change all dependencies and libraries to try to solve it, but nothing worked.</p>
  
  <p>Here is build.gradle Project</p>
  
  <pre><code>buildscript {
  
      repositories {
          google()
          jcenter()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:3.1.1'
          classpath 'com.google.gms:google-services:3.2.1'
  
  
          // NOTE: Do not place your application dependencies here; they belong
          // in the individual module build.gradle files
      }
  }
  
  allprojects {
      repositories {
          maven { url 'https://jitpack.io' }
          google()
          jcenter()
      }
  }
  
  task clean(type: Delete) {
      delete rootProject.buildDir
  }
  </code></pre>
  
  <p>And this is my build.gradle Module:app</p>
