Duplicate Class Between JAR Libraries provided

Hey,

When I build the Android Studio project, I get the following error. I copied your source and libs into my project and updated my build.gradle dependencies.

Hi,
did you try to exclude the duplicated jars?

Hi,
did you try to exclude the duplicated jars?

Hey, I tried following the "implementation library-name.jar { exclude: ... }" syntax but it didn't seem to work with JAR libraries. I also tried the "force" property without any success. I eventually ended up accessing the JAR directory and physically deleting one of the duplicate libraries there (the org.apache.commons).

I'm not super familiar with gradle and android. Is there a better way to handle this duplicate issue? Note that both JAR libraries are necessary for the code to run, but they just contain a duplicate dependency.
