Is there a way to find out what particular BUILD file an error is coming from?

What error are you seeing? Usually the error messages do give useful context

If the BUILD file path is not in the error message, that's a bug.

What was your pants command?
So you have some BUILD file referencing
requirements/python:structlog
, it looks like? And Pants is complaining that this is not a valid target address?

Yes, but I have to look in the fake traceback to find it out.. And,
./pants --changed-since=0e9f53550398c7c39b5b44662d353ee56628f3d6 --changed-dependees=transitive --tag=+foo release
(this is 2.12, btw, it’s part of my neverending quest to migrate from 2.6 🙂 )
And, to be fair, the path there should be resolved:
in pants.engine.internals.graph.resolve_dependencies (lib/tests/unified_threat_feeds/integration/test_s3_feeds.py:../../../unified_threat_feeds_tests
(I did notice that path after I asked, btw, because I found it by grepping for the
:structlog
and then searched the error message for the path…)

Still that could be a better message!

It definitely could be. This one in particular was a mismerge, as I’m working on upgrading things other people are actually working. 🙂

@happy-kitchen-89482 the new error messages are in Pants 2.13. This was a ~week project to make these much better

When’s that supposed to come out, I’m already updating across 6 versions, might as well wait a bit and do 7 🙂

@witty-crayon-22786 hopefully end of next week? We know we have at least one more rc for a performance improvement, otherwise it's been used by several orgs for 2 weeks
