hello guys - I'm little confused about release history as I see here: https://pypi.org/project/pantsbuild.pants/#history that you released version 1.11 and 1.12 - is that because of some roadmap/release cycle?

Is there a particular reason we use Antlr 3 instead of Antlr 4, beyond not keeping the version up-to-date? I’m investigating Py3 failure and think we may need to upgrade, but not sure yet

does anyone successfully use pants keeping multiple versions of 3rdparty python libraries around? it seemed to kinda work, but when our ci script ran

./pants test lint ::

(roughly) it tried to import both versions of the library and failed.

ran into an issue related to https://github.com/pantsbuild/pants/issues/146

Could I bother someone with permissions to fork https://github.com/alexcrichton/futures-timer into pantsbuild, and give me push rights? 🙂

@enough-analyst-54434 I’m going to take a stab at https://github.com/pantsbuild/pants/issues/6782, do you have any general suggestions?

weird question about shading, how would i accomplish something like this for my big jar i create? https://stackoverflow.com/questions/9069138/apache-cxf-client-loads-fine-in-eclipse-but-standalone-jar-throws-nullpointerexc/9069435#9069435

also thanks a lot @enough-analyst-54434 for https://github.com/pantsbuild/pants/pull/6894, i had been telling people this was the case without checking and this issue may have tripped me up several times when debugging

yeah. Thats pretty nice

Hey, how are people sharding/distributing CI builds in larger monorepos using Pants?

was pointed at https://www.pantsbuild.org/orgs.html#continuous-integration a few days ago… can anyone explain why that script minimizes the set of targets it tests?

does pants support the Build Tool Protocol or is it planned ?

can somebody help me with PR: https://github.com/pantsbuild/pants/pull/6974 ? I am trying to provide a gRPC support for pyhon code generation, but probably i’ve missed some place, where I should register new backend code?

Hi, anyone here know the stories around using pants for big scala.js projects using webpack to manage JavaScript dependencies? We are using

sbt

with

scalajs-bundler

plugin which offers a bundling mode https://scalacenter.github.io/scalajs-bundler/reference.html#bundling-mode-library-only that would not make webpack choke on the large JS output from scala.js. I am wondering if there is something similar in pants?

hey guys! Context I’m trying to produce a combined coverage from unit, integration, blackbox tests for multiple projects that share same code and having a bit of trouble understanding how it can be done properly using

pants

. Details - unit and integration tests are collecting coverage via

./pants test

with

--test-junit-coverage-processor=jacoco --test-junit-coverage

options - for blackbox I couldn’t figure out how to use pants natively, so it’s done using

JaCoCo

agent to create

foo.exec

and

bar.exec

files with

java -javaagent:jacocoagent.jar -jar dist/<path to foo.jar>

for bundles that are created by

./pants bundle

and then combined report can be generated via

java -jar jacococli.jar report foo.exec bar.exec --classfiles dist/bar.jar --classfiles dist/baz.jar --html <dir to output report to>

Questions - Is there a way to run bundles using pants and collect coverage data and merge reports for multiple different bundles? - if not, where one can find classfiles that

pants

is using to produce report so that one can specify them when creating a combined report?

jacoco.exec

can be found in

.pants.d/junit/_runs/..

folder but I don’t see any classfiles there,

tmp*.jar

don’t seem to contain the info needed as well, and .pants.d/compile folder contains too many classes I don’t care about and even with filters it seems like some deduplication might be needed

what does

a minimal covering set of targets

means ? I'm trying to understand what

minimize

does but I'm not sure.

is it like, "all leaves" of the tree ?

I know what a covering tree is for a given graph, is the notion related ?

@aloof-angle-91616: sorry for the miscommunication on https://github.com/pantsbuild/pants/pull/7015 ... i wasn't reading as closely as i should have.

Hello everyone! I’m new to pants and I just saw other people using it and found it very interesting.

I was thinking into packaging with pantsbuild a customized jupyter notebook as pex file, to give to students to run with the same libraries needed for the exercises. Suggestions on what to read and use for this to happen?

Hello. Was pointed at https://www.pantsbuild.org/orgs.html#continuous-integration a few weeks ago… can anyone explain why that script minimizes the set of targets it tests?

hi, I have a little problem. If I compile twice the same target, first time it is a success, second time it fails as if the dependency is not in the classpath. I've set up a minimal example here : https://github.com/lgirault/test-pants-coursier

if I do not use coursier, it works !

Is there a handy way to either: 1. Materialize a

resources

target into a directory 2. Make a zip file of a

resources

target ?

does anyone use pants to do something like package wheels containing functionality from

python_library

targets?

pants itself does that

for its own wheels
