title: BoundBox fails to generate classes
body: <p>I made a simple project to test BoundBox. I'm using Android Studio Structure is default:</p>
  
  <pre><code>src
  -- instrumentTest
  -- -- java
  -- -- -- ItemListActivityTest
  -- main
  -- -- java
  -- -- -- com.example.test.dummy
  -- -- -- -- ItemDetailActivity
  -- -- -- -- ItemDetailFragment
  -- -- -- -- ItemListActivity
  -- -- -- -- ItemListFragment
  -- res
  </code></pre>
  
  <p>This is my <strong>build.gradle</strong>:</p>
  
  <pre><code>buildscript {
      repositories {
          mavenCentral()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:0.6.+'
      }
  }
  
  apply plugin: 'android'
  
  repositories {
      mavenCentral()
  }
  
  dependencies {
      compile 'com.android.support:appcompat-v7:+'
      compile 'com.android.support:support-v4:18.0.0'
  
      instrumentTestCompile "org.boundbox:boundbox-library:1.2.0"
  }
  
  android {
      compileSdkVersion 18
      buildToolsVersion "18.1.1"
  
      defaultConfig {
          minSdkVersion 11
          targetSdkVersion 18
      }
  }
  </code></pre>
  
  <p>Test class is simple too:</p>
  
  <pre><code>import android.test.ActivityInstrumentationTestCase2;
  import org.boundbox.BoundBox;
  import com.example.test.dummy.ItemListActivity;
  
  
  @BoundBox(boundClass = ItemListActivity.class)
  public class ItemListActivityTest extends ActivityInstrumentationTestCase2&lt;ItemListActivity&gt; {
  
      public ItemListActivityTest() {
          super(ItemListActivity.class);
      }
  
  }
  </code></pre>
  
  <p>The problem is that when i add an annotation, classes are not generated automatically as it says in BoundBox' wiki. So i'm trying to run <code>gradlew compileTest</code> to generate classes and getting an error:</p>
  
  <pre><code>... more info log ...

  An annotation processor threw an uncaught exception.
