I'm having trouble adding the Jackson Parser dependency to my project.

Currently I'm using these lines of code on my build.gradle:

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'


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.

The problem was running the project on the emulator, this error showed up in Messages in Android Studio:

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

com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/NOTICE File1: C:\Users\Igor.gradle\caches\modules-2\files-2.1\com.fasterxml.jackson.core\jackson-databind\2.7.2\84ffa765dd258dbab8695963c41308b054f3a1cb\jackson-databind-2.7.2.jar File2: C:\Users\Igor.gradle\caches\modules-2\files-2.1\com.fasterxml.jackson.core\jackson-core\2.7.2\8b8310381b690e317f5f0574e9b2dd7034778b4c\jackson-core-2.7.2.jar


I tried to left only the databind library but I got no lucky with that. Same error. 

compile 'com.fasterxml.jackson.core:jackson-databind:2.7.2'


I tried Build -> Clean Project and deleting the .gradle/cache but no luck either.


I have no clue what this could be. Any suggestions?

Add 

android {
...
packagingOptions {
exclude 'META-INF/NOTICE' // It is not include NOTICE file
exclude 'META-INF/LICENSE' // It is not include LICENSE file
}
...
}

in your build.gradle .

To resolve the problem entirely I added all of these:

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