Android Question Help request for desugaring a library

[abilio486software]

Hi,

I'm trying to desugar a Verifone .aar

classes.jar is already extracted:

JAR to desugar

If possible, could someone help me to desugar this .jar?

Many thanks

something fishy about this one, i think. i've used erel's desugarer a few times without incident. (i just tried a file i had to make sure i wasn't missing something. it desugared find.) your classes.jar file, however, caused a lot of commotion:

I've sent you the jar with an email as it is larger than allowed in the forum.
