title: Running Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'
body: <p><strong>Running Error</strong>  Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'<br>
  So I'm continuously receiving a gradle build error upon trying to run my project. I have searched for other solutions and some say that adding:</p>
  
  <pre><code>packagingOptions {
      exclude 'META-INF/NOTICE'
      exclude 'META-INF/LICENSE' // will not include LICENSE file
      // as noted by @Vishnuvathsan you may also need to include
      // variations on the file name. It depends on your dependencies.
      // Some other common variations on notice and license file names
      exclude 'META-INF/notice'
      exclude 'META-INF/notice.txt'
      exclude 'META-INF/license'
      exclude 'META-INF/license.txt'
  }
  </code></pre>
  
  <p>But it doesn't work for me.The Error as below:
  Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.</p>
  
  <blockquote>
    <p>com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/rxjava.properties</p>
  </blockquote>
  
  <pre><code>**File1: E:\Workspace_Android\TravelStory\app\build\intermediates\exploded-aar\cn.bmob.android\bmob-sdk\3.5.0\jars\classes.jar
