transformResourcesWithMergeJavaR

Error:Execution failed for task ':Autobahn:transformResourcesWithMergeJavaResForDebug'.

com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/ASL2.0 File1: /Autobahn/libs/jackson-mapper-asl-1.9.7.jar File2: Autobahn/libs/jackson-core-asl-1.9.7.jar

I have been added

packagingOptions { exclude 'META-INF/DEPENDENCIES' exclude 'META-INF/NOTICE' exclude 'META-INF/LICENSE' exclude 'META-INF/LICENSE.txt' exclude 'META-INF/NOTICE.txt' exclude 'META-INF/ASL2.0' }

How do I solve this problem？
