title: annotationprocessor and apt configure equivalent
body: <p>I'm using <code>AndroidAnnotaion</code>, but due to Android Studio 2.3 and Gradle 2.3.0, they said <code>android-apt</code> was obsoleted. And <code>annotationProcessor</code> is a new one. so, I want to know how can I configure <code>annotationProcessor</code> like I do with <code>apt</code> before.</p>
  
  <p>If I misunderstand something, please help.</p>
  
  <p><strong>So, before...</strong></p>
  
  <pre><code>apply plugin: 'android-apt'
  
  dependencies {
  
      def AAVersion = '4.2.0'
      apt "org.androidannotations:androidannotations:$AAVersion"
      compile "org.androidannotations:androidannotations-api:$AAVersion"
  }
  
  apt {
      arguments {
          library 'true'
      }
  }
  </code></pre>
  
  <p><strong>and now...</strong></p>
  
  <pre><code>dependencies {
  
      def AAVersion = '4.2.0'
      annotationProcessor "org.androidannotations:androidannotations:$AAVersion"
      compile "org.androidannotations:androidannotations-api:$AAVersion"
  }
  </code></pre>
