wonder if that is still necessary... and whether it would actually help.

In the new PytestRun task

--fast

is deprecated and doesn’t actually do anything

that's probably good news.

@happy-kitchen-89482 : one thing i've thought about is moving the contrib tests under infrastructure similar to https://github.com/pantsbuild/pants/blob/master/tests/python/pants_test/projects/test_testprojects_integration.py

so that they're sharded using the top-level sharding we use for integration testing

witty-crayon-22786

03/30/2017, 9:16 PM

and we get more even distribution

(for that matter, not sure why we have unit tests split out at this point)

witty-crayon-22786

03/30/2017, 9:17 PM

... that might be the easier short term fix: merge integration and unit to add two shards there, and then drop one to shard contrib.

happy-kitchen-89482

03/30/2017, 9:26 PM

Yeah, I’m not sure why we don’t just run

./pants test :: <sharding spec>

at this point

Why we need to split things out just-so in a shell script

I think this is a very high profile use that should be on Friends of Rust page. Maybe contact pants-devel and ask them for a blog post that we can link?

hi, i’m trying to figure out how to configure a nexus proxy. I found http://www.pantsbuild.org/setup_repo.html#nexus-as-proxy but it doesn’t specify what to put in pants.ini. Does anyone know? Or know how I can figure this stuff out?

@acoustic-crowd-90154 You can specify a custom ivy_settings in pants.ini https://github.com/pantsbuild/pants/blob/92df6d938cbe535d34cd8231aaa6ba3eb19da311/pants.ini#L86

is jdk part of the fingerprint? saw some test failure like this,

xsbti/Logger

is from the shaded zinc jar, that was probably compiled by jdk8 and cached. test tries to compile with jdk7

Copy code

java.lang.UnsupportedClassVersionError: xsbti/Logger : Unsupported major.minor version 52.0
                       	at java.lang.ClassLoader.defineClass1(Native Method)

hmm, wonder why it didn't fail before
