Android studio hapi fhir validation, checkDebugDuplicateClasses error

Question

I am trying to build a simple android project in which I want to use some hapi-fhir dependencies. However, despite the built is successful, when I am running the application I get a duplicate classes error. The dependencies I am trying to add are the following:

implementation 'ca.uhn.hapi.fhir:hapi-fhir-base:4.1.0'
implementation 'ca.uhn.hapi.fhir:hapi-fhir-structures-dstu2:4.1.0'
implementation 'ca.uhn.hapi.fhir:hapi-fhir-structures-r4:4.1.0'
implementation 'ca.uhn.hapi.fhir:hapi-fhir-validation-resources-r4:4.1.0'
implementation group: 'ca.uhn.hapi.fhir', name: 'hapi-fhir-validation', version: '4.1.0'

After commenting out each one I conclude that the issue is deriving from the last one (hapi-fhir-validation).

I have also added this dependency to prevent some previous issue.

implementation 'androidx.multidex:multidex:2.0.1'

While running the failed tasks are the following:

FAILURE: Build completed with 2 failures.

Any advice on how to proceed will be very useful. Please let me know if you need any more information.

Thank you in advance!!

Answer 1

Currently made this work by importing the dependency while excluding the one that appeared as duplicate as follows:

implementation('ca.uhn.hapi.fhir:hapi-fhir-validation:4.1.0'){
    exclude group: 'commons-logging', module: 'commons-logging'
}

instead of:

 implementation 'ca.uhn.hapi.fhir:hapi-fhir-validation:4.1.0'
