I imported EBS Sdk in my project.Now gradle building is success but while running

  Error:Execution failed for task':app:transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/android/volley/AuthFailureError.class**

this exception occurs.

The following is the build.gradle of both app and the module i have searched and tried all the possiblities but i am not getting the result
