How to identify required . jar files ?

Hello,
on unity android, if I remove a .jar or .aar file, does unity throw an error in the build process if that jar is required by a plugin or does the plugin just stops working in the game ?

( I have .jar files conflict & to I need to know if I a remove a jar that is used by a plugin, will the plugin stop working inside the game or do I get an immediate error in the build telling me there is a missing jar file )

Thanks

If jar is missing you will not get any error during the build process unless there is a script checking for jar in postProcessBuild functions. You will get error at runtime or app will crash saying “class not found” in log.
if there are multiple jar files with same class you will get error during the build process saying something like “bla bla bla already added bla bla bla”.
