title: Multiple dex files define <my package>/BuildConfig, can't find the cause:
body: <p>I'm using the new gradle build system and I'm facing the following problem:</p>
  
  <pre><code>UNEXPECTED TOP-LEVEL EXCEPTION:
  com.android.dex.DexException: Multiple dex files define Lcom/kibo/mobi/BuildConfig;
      at com.android.dx.merge.DexMerger.readSortableTypes(DexMerger.java:594)

  </code></pre>
  
  <p>Priniting the dependencies I can't see anything, here they are:</p>
  
  <pre><code> firstDebugCompile - ## Internal use, do not manually configure ##
   \--- KiboGradle:KiboSDK:unspecified
   +--- KiboGradle:TextInputAPI:unspecified
   +--- KiboGradle:VoiceImeUtils:unspecified
   +--- com.google.android.gms:play-services:5.0.77
   |    \--- com.android.support:support-v4:19.1.0
   +--- com.squareup.picasso:picasso:2.3.2
   +--- com.google.code.gson:gson:2.2.4
   \--- com.crittercism:crittercism-android-agent:4.5.1
  </code></pre>
  
  <p>I tried to verify that the problem is not a duplicate support library so I tried to add:</p>
  
  <pre><code>compile ('com.google.android.gms:play-services:5.0.77'){
      exclude module: 'support-v4'
  }
  </code></pre>
  
  <p>Which resulted in errors that some of the <code>support-v4</code> library classes can't be found, so this library not getting compiled from any other location.</p>
  
  <p>One thing I had in mind that could cause this problem is the fact that I using the <code>Flavors</code> feautre in oreder to create several versions of my application with different resourse files.</p>
  
  <p>And when I look at the file that is in the error I see this:</p>
  
  <pre><code>**
  * Automatically generated file. DO NOT MODIFY
  */
  package com.kibo.mobi;
  
  public final class BuildConfig {
    public static final boolean DEBUG = Boolean.parseBoolean("true");
    public static final String PACKAGE_NAME = "com.kibo.mobi.test.official";
    public static final String BUILD_TYPE = "debug";
    public static final String FLAVOR = "liverpool";
    public static final int VERSION_CODE = 1;
    public static final String VERSION_NAME = "1.0";
  }
  </code></pre>
  
  <p>So the package in of the file and the package specified in String value are not the same.</p>
  
  <p>Can anyone see any issues in my configuration that could cause this problem?</p>
