has anyone successfully installed

1.19.0

on macosx

10.14.6

? I get this error:

thread panicked while processing panic. aborting.
[1]    36512 illegal hardware instruction  ./pants

I could use help. I'm trying to import this repo: https://github.com/KaoruDev/learning_pants_build via intellji and get stuck on this screen:

image.png

additionally, couldn't figure out how to load the examples dir in the pantsbuild/pants repo

is that

pants-demo

directory the place you cloned https://github.com/KaoruDev/learning_pants_build to?

yeah, sorry the dir name != repo name

but they're the same

running

./pants compile mather/src/main/scala:adder

works

help again, 😞 I'm trying to run a scala test run on: https://github.com/KaoruDev/learning_pants_build but i keep getting this error:

The tests failing in this build are flaky could someone restart the shards https://travis-ci.org/pantsbuild/pants/builds/581814435?utm_source=github_status&utm_medium=notification

so all of the restarted shards failed again https://travis-ci.org/pantsbuild/pants/builds/581814435

./build-support/bin/get_ci_bootstrapped_pants_pex.sh ${BOOTSTRAPPED_PEX_BUCKET} ${BOOTSTRAPPED_PEX_KEY_PREFIX}.${BOOTSTRAPPED_PEX_KEY_SUFFIX}" failed and exited with 1

I assume it couldn't get a pex file, for some reason, not sure(?).

hello! trying to compile simple project with scala 2.13. source of project is on https://github.com/k-bespalov/pants-scala-helloworld try to compile via command

./pants compile src/main:hello --scala-version=custom --scala-suffix-version=2.13

and get error

zinc[zinc-only](src/main:hello) failed: sequence item 0: expected str instance, ArtifactClasspathEntry found
FAILURE: Compilation failure: Failed jobs: zinc[zinc-only](src/main:hello)

anybody knows what does it mean? and how I can fix it? if I remove BUILD.tools file and compile with

--scala-version=2.12

compilation is successful, but when I construct jar via

binary

command, jar doesn’t contain scala library and I get ClassNotFoundExceprion(this is my next question 😄 ). thank you in advance

an open source user looking to migrate to pants is instead using bazel, and was extremely specific when describing what wasn't quite working for them, and how the pants documentation was lacking. this inspired me to think of: - making a github issue to develop a strategy to improve the first-time experience with pants - sending a link to the github issue to

pants-devel

- iterating on that to produce tickets for a github project. are there any communication channels i'm missing? i'd drop a link in this channel too.

I'm evaluating pants to build a multi library python project. Specifically I'm looking for something like a Maven multi-module project. Are there any examples on how to do the same with pants and python?

Pants is a multi-library python project and dogfoods itself for its own builds:

It's a fairly complex project though; so - a bit ironically - it is probably not the best example of how you might set your project up. You might start looking here though while reading through https://www.pantsbuild.org/python_readme.html and https://www.pantsbuild.org/3rdparty_py.html.

hello, i'm thinking through fun ideas for twitter's hackweek in a couple weeks. the below message was asking the #engine channel purely about work on the v2 engine (the newer, much more fun method of writing pants tasks) -- but i (and any other twitter engineers i can persuade to join me) would also love to know any other sore spots users have with pants that are perchance hackweekable: https://pantsbuild.slack.com/archives/C0D7TNJHL/p1568482865012800 feel free to reply to this thread or DM me!

Hi team, I wonder if anyone could give me some pointers in resolving a "Failed to cache distribution" error when running a pex generated out of my build? It's a pex that worked originally, then we replaced a dependency (tensorflow) with a different build of it (intel-tensorflow) and hit this issue.

If I subclass Optionable and implement

register_options

, does that function get magically called?

general python question: when we define a

datatype

with tuples of

("field_name", type_specifier)

, what's the best way to make some of those fields have defaults?

in the pex commit I'm working on now that I got from @aloof-angle-91616 he overrode

__new__

, but it seems like there might be a better way to do it?

Hi. I have a question about pants and Scala. We want to remove unused dependencies from our BUILD files to speed-up builds. We're using Scala and planning to use strict deps. I don't see anything which helps with this in Pants options, but maybe I miss something or there's a tool which already does this? The closest thing is "pants dep-usage", but it's not exactly what we need. Or, maybe, there's a tool which can construct BUILD files by analyzing .scala + .java files in a directory? If there are no such tools, what do you think is the best approach to build such a tool? Maybe we can use some info which pants already provides?

What does python lint eval actually do?

Does pants have support for running the unittests on kubernetes?

or does pants support distributed unittests?

it does for Python, yes. it is very experimental, but Pants is dogfooding that support to run its own tests

@witty-crayon-22786 Thanks for responding to me. Do you have a document about the architecture?

What branch do I base my fix on? master?

does anyone have any input on this proposed change to add

--transitive

to all `ConsoleTask`s? it would allow tasks such as

filedeps

to work transitively or intransitively, an option which didn't exist before. https://github.com/pantsbuild/pants/pull/8224

Hey pants community, I’d like to fix a workflow pain I’ve had since started working on pants recently: The python code isn’t automatically formatted, yet our pre_commit hook complains for some formatting issues, leaving the programmer with no other option than manually formatting their code like an animal. Another minor issue I have is that our formatting isn’t very consistent across files, and even within files in some places. I think the solution for this problem is to use a tool to automatically format our code, run it now and commit that and add it to the pre_commit hook to avoid regressions in the future. This way, developers can add that tool to their text editor/IDE if they want to and never think of it again; and we all enjoy a consistently formatted codebase. Assuming everything makes sense so far, the next step is to decide which tool to use and which settings. From a bit of research, the two main contenders seem to be: • yapf (https://github.com/google/yapf) <- quite flexible in the way it’s configured • Black (https://github.com/psf/black) <- more opinionated
