Getting checkDebugDuplicateClasses error when building application with another third-party dependency

[mohammedhammoud]

I'm getting the following error when trying to build stario10 and with another third-party dependency.

FAILURE: Build failed with an exception.

Any ideas on how to solve this?

I have a minimum android project with the current failure setup: https://github.com/mohammedhammoud/geidea-stario10-duplicate-class-deps-error

Is it possibile to use -keeppackagenames when compiling com.starmicronics:stario10 for distribution @bandit-ibayashi? (Sorry in advance for pinging you 😄 ).

A similar issue was also fixed with flattenpackagehierarchy here https://github.com/helpcrunch/android-sdk-demo/issues/33

[bandit-ibayashi]

We much appreciate for your report and suggestion.

For the tentative solution, would the following workaround help you? https://stackoverflow.com/questions/59991168/duplicate-class-names-in-two-external-third-party-obfuscated-libraries

[mohammedhammoud]

That solution did not work. I contacted geidea and they solved it at their end by adding flattenpackagehierarchy. I suggest you do the same.

@mohammedhammoud Thank you for trying the solution and I'm afraid that is not work for you. We will respond to this in our next update. Thank you for your patience!

@mohammedhammoud We have updated our library to avoid obfuscation to unnecessary parts as version 1.0.1. We would appreciate your confirmation that this update will resolve this issue.

Thank you for your patience!
