Pants

to be fair, the most important thing is that it continues to work post engine refactor

but the difference between patterns and a list of paths is just whether the match is the prefix of the path (`$buildroot/src/java`) or anywhere in the path (`$buildroot/**/src/main/java`)

...and whether we know upfront where all sourceroots are. but that looks like a special case

It's a special-ish case, there are other non-lazy uses, I think

i've seen that as well, seemingly randomly

...oh no. the release process does the npm fetch

it's... going to be a little while. i'm on my phone.

alright, we have an 0.0.53 release. but it looks like the changelog script might generate bad rst

@benjy - you need to walk back up the whole trace

The issue is src/python/pants/backend/jvm/subsystems/jvm_tool_mixin.py

jvm_tool_mixin.py doesn't use anything from option in my commit
