title: Using android Parceler library with minifyEnabled
body: <p>Whenever I try to minify my project that makes use of the <a href="https://github.com/johncarl81/parceler" rel="nofollow">parceler library</a>, I cannot build a release apk because of a lot of warnings from proguard. For example:</p>
  
  <blockquote>
    <p>Warning:org.parceler.transfuse.gen.FilerResourceWriter: can't find referenced class javax.tools.FileObject</p>
  </blockquote>
  
  <p>I don't even make use of most of the libraries reported in this messages. What I'd like to know is if someone has encountered this problem and managed to solve it.
  I tried to use -dontwarn to suppress all messages, but it does not seems correct, and besides it makes my app crash in rare cases (which makes me thing that some of the warning messages are indeed correct, but I'd like the library to keep the needed classes automatically).</p>
  
  <p>My gradle script is as follows:</p>
  
  <pre><code>apply plugin: 'com.android.application'
  
  ...
  
  dependencies {
      ...
      compile 'org.parceler:parceler:1.0.3'
  }
  </code></pre>
