Any ideas on how to solve Duplicate class with android jetified?

I’m getting the following error when trying to build an android application with two third-party dependencies.

FAILURE: Build failed with an exception.

Does anyone know how solve this issue?

I have a minimal android project if anyone can help me solve this: https://github.com/mohammedhammoud/geidea-stario10-duplicate-class-deps-error

Answer

This is now solved. I contacted the maintainers of the libraries, they added flattenpackagehierarchy to proguard which solved it.
