Paolo Patierno commented on KAFKA-5536:
---------------------------------------

Thanks Ismael !

1. Good. I can recover the previous work I have done using argparse4j. In any case my idea is to mimic the same behaviour we have with the joptsimple lib in order to avoid problems.
2. Regarding sharing the code, the CommandLineUtils leverages on the joptsimple lib so it's not possible just move it to use argparse4j in Java and then sharing with other Scala tools (even because the migration will be slow, tool by tool and not all together). So it seems that the better solution for now is just rewriting for the tools module.

Let's see how things will evolve on TopicCommand, the first tool that will be the subject of this big migration.

> Hi,
> is there any specific reason why tools are splitted between Java and Scala implementations ?
> Maybe it could be better having only one language for all of them.
> What do you think ?
> Thanks,
