title: Dagger not generating Component classes
body: <p>I have tried a great deal debugging this issue but unable to find the cause. Dagger simply doesn't create the DaggerComponent classes. I've checked SO for duplicates but none of the solutions provided worked.</p>
  
  <p><strong>project's build.gradle</strong></p>
  
  <pre><code>buildscript {
      repositories {
          jcenter()
      }

          classpath 'me.tatarka:gradle-retrolambda:3.2.3'
          classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
          classpath 'me.tatarka:gradle-retrolambda:3.0.1'
  
          // NOTE: Do not place your application dependencies here; they belong
          // in the individual module build.gradle files
      }
  }
  
  allprojects {
      repositories {
          jcenter()

  <p>Dagger is failing to generate the component class in my Application class. I've tried clean building, I've tried invalidating cache but nothing works.</p>
