title: Cannot build graph with Dagger 2
body: <p>I am trying to create the dependency graph with Dagger 2 based on the example of the dagger 2 website (the coffeeMaker and the source is here : <a href="https://github.com/google/dagger/tree/master/examples/simple" rel="nofollow">https://github.com/google/dagger/tree/master/examples/simple</a>). </p>
  
  <p>I created the component as stated in the site : </p>
  
  <pre><code>@Component(modules = {DripCoffeeModule.class})
  public interface CoffeeShop {
      CoffeeMaker maker();
  }
  </code></pre>
  
  <p>The annotation processor correctly generates the files (in the target directory) but I am unable to find the <code>DaggerCoffeeShop</code> class. (Ctrl + space) does not work. </p>
  
  <p>How can I solve this problem? </p>
