How are people working with pyflink/pyspark and jars? I've seen a few references to

experimental_wrap_as_resources

but I've never managed to get that to work. I would like to be able to include jars in the sandbox when running tests or cli tooling. At the moment, the only solution I have is including the jars in the sourcetree and treating them as resources, but that feels icky, and now I need to build a custom jar, it isn't really workable (I guess I can package the custom jar, then copy it to the source tree from dist. Yuck.)
