title: Android Studio trouble setting up Jackson Parser on gradle
body: <p>I'm having trouble adding the Jackson Parser dependency to my project.</p>
  
  <p>Currently I'm using these lines of code on my build.gradle:</p>
  
  <pre><code>compile 'com.fasterxml.jackson.core:jackson-core:2.7.2'
  compile 'com.fasterxml.jackson.core:jackson-annotations:2.7.2'
  compile 'com.fasterxml.jackson.core:jackson-databind:2.7.2'
  </code></pre>
  
  <p><br>The only Class I need is the ObjectMapper that I know it is in databind package. When I added these lines in the gradle I pressed the sync and everything did correctly.</p>
  
  <p>The problem was running the project on the emulator, this error showed up in Messages in Android Studio:</p>
  
  <blockquote>
    <p>Error:Execution failed for task
    ':app:transformResourcesWithMergeJavaResForDebug'.</p>
    
    <blockquote>

  <p><br>I tried to left only the databind library but I got no lucky with that. Same error. </p>
  
  <pre><code>compile 'com.fasterxml.jackson.core:jackson-databind:2.7.2'
  </code></pre>
  
  <p><br>I tried <code>Build -&gt; Clean Project</code> and deleting the .gradle/cache but no luck either.</p>
  
  <p><br>I have no clue what this could be. Any suggestions?</p>
