and would there be an issue if I added append_only_caches support to InteractiveProcess for when run_in_workspace=False ?
(which is where some coursier files are, context is for scala repl)

…alllthooough. the JVM to spawn would still be in a named cache.
so yea.

also I think I'm really really close to finishing PyO3. Stu helped me this morning to figure out my main blocker, how to port the
with_scheduler
context managers
<http://interface.rs|interface.rs>
is almost green, and then just have to finish
<http://intrinsics.rs|intrinsics.rs>
and
<http://nodes.rs|nodes.rs>
So might be worth waiting before dabbling with that code

I’m already dabbling in the InteractiveProcess code.
just a WIP PR. it’ll need to be split any way.
current issue is that the working directory is set to a temp dir under the system tmp dir, but the files are materialized to a tmpdir under .pants.d

so two tmp dirs, which is weird
(I had to thread run_in_workspace through from ReplRequest)

is the initial inference PR landable? that would let others experiment.
but i guess we’re not doing thirdparty inference yet huh

https://github.com/pantsbuild/pants/pull/12986 may be of interest for third-party artifact Scala support. That is WIP
scala_artifact
support.
