Duplicate files copied to protobuf.meta APK on Googlemap for Business

Question

I follow the instructions here to implement Googlemap for business (Option 2: Import the SDK as a library module):

https://developers.google.com/maps/premium/android-get-started When I try to start the application, it returns me this error:

* What went wrong: Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'. > com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK protobuf.meta File1: /Users/name/.android/build-cache/f333e5a1ed5f958c1e7d100de7935a31efd81cd6/output/jars/classes.jar File2: /Users/name/Documents/name/project-name/googlemapssdkm4b_lib/build/intermediates/bundles/default/classes.jar 

Here is my gradle file:

'io.card:android-sdk:5.5.1' } 

I tried to put

 packagingOptions { pickFirst 'protobuf.meta' } 

and the error above just disappeared, but when the application is launched, it will crash at runtime, saying that it cannot find com.google.android.m4b.maps.MapFragment

I use Android Architecture components in my project that may contain Guava, but I already exclude it from googlemapssdkm4b_lib and it still does not work.

Has anyone here used Googlemap for business and have encountered this problem before?
