I think the needs discussed over here are basically for running Spock functional tests. No back and forth.

When executing the

bundle

goal with the

--bundle-jvm-deployjar

option, what is expected to happen? My simplistic view is that it first generates all the jars as normally, and then starts merging those ..

Thanks @high-advantage-47550 @full-kilobyte-93429 it occured to me after I got home last night that might be the case and confirmed it this morning by moving the repo out of my home dir. Adding

[compile.zinc] 
args: [
    '-S-Xmax-classfile-name', '-S128'
      ]

also did the trick.

Also, I noticed the

test-prep-command

and was wondering how it is used .. Could it technically spin up docker images for example when running

test ..:integration

? The question then remains how to spin it down after the run has completed ..

Hey everyone, I'm currently trying to figure out how to add a custom pants goal (sorry not super familiar with the terms yet) using a custom plugin. I have been trying to follow this: http://www.pantsbuild.org/howto_plugin.html but have hit a wall. Basically I have a simple python function I want to be able to invoke using

pants setup

. My directory structure looks like this:

build-support
    plugins
        testplugin
            __init__.py
           register.py
           targets
               __init__.py
               setup_k8s.py    
pants.ini

In my

register.py

I have this

from pants.build_graph.build_file_aliases import BuildFileAliases
from testplugin.targets.setup_k8s import setup_k8s

def build_file_aliases():
    return BuildFileAliases(
        objects={
            'setup': setup_k8s
        }
    )

in

setup_k8s

I have this:

def setup_k8s():
    print('it worked!')

and in

pants.ini

I have this:

[DEFAULT]
pants_version: 1.1.0

pythonpath: [
    '%(buildroot)s/build-support/plugins',
  ]
backend_packages: [
    'testplugin',
  ]

However when I do

./pants setup

I get

Unknown goals: setup
Use `pants goals` to list goals.
Use `pants help` to get help.

If anyone can give me any insight into what I'm doing wrong that would be awesome 🙂

it looks like you’re creating a new goal, rather than a build file alias

http://www.pantsbuild.org/dev_tasks.html might be helpful

yes this looks more like what I was trying to do, thanks tons @fast-megabyte-33579!

@victorious-potato-60449 I found that most of the time all you need is a task, not actually a new goal

I see, I think I need to familiarize myself more with what these terms mean as well

does a task have to be written in Python? Or could you use Go for example?

Afaik extending pants needs to be done in python. But nothing prevents you from calling Go from python ..

of course, just wondering if it was a native thing or not 🙂

alright so I'm running into problems trying to use boto3 inside a custom plugin with a custom task, I'm following this pattern: http://www.pantsbuild.org/3rdparty_py.html. Here is my directory structure:

3rdparty/
    python/
        BUILD
        requirements.txt
build-support/
    plugins/
        testplugin/
            targets/
                setup_terraform.py
            BUILD
            register.py

in

3rdparty/python/BUILD

I have

python_requirements()

in

3rdparty/python/requirements.txt

I have

appdirs==1.4.0
boto3==1.4.4
botocore==1.5.8
docutils==0.13.1
jmespath==0.9.1
packaging==16.8
pyparsing==2.1.10
python-dateutil==2.6.0
s3transfer==0.1.10
six==1.10.0

in

build-support/plugins/testplugin/BUILD

I have

python_library(
    dependencies = [
        '3rdparty/python:boto3'
    ]
)

However pants is still not able to find a module named

boto3

when I do

import boto3

in my code. What am I missing?

what is

./pants list ::

telling you?

that's cool, thanks for help though

@purple-oil-45048 commented on @victorious-potato-60449’s file https://pantsbuild.slack.com/files/U438RFXCP/F42JVSG4T/Untitled.txt: maybe https://github.com/twitter/commons could help you a bit -- they seem to do similar things

@victorious-potato-60449 I've done this by modifying the bootstrap script (

pants

in root of repo) to install additional requirements files when bootstrapping the python venv.

is there any existing tooling out there for publishing/syncing a subset of a pants repo as a separate git(hub) repo?

not pants specific iirc tho

ah, still useful! thanks!

Do you guys ever get requests for testng support?

hi. I see that most tasks generate output into .pants.d. Is there a recommended way to find this output besides running find commands from the command line? Maybe a goal that dumps the current directory for a target? I would like to have scripts use output generated by pants tasks. My example is running babel against .jsx files. I’d like to copy these generated .js files somewhere.

@straight-waiter-86090 Instead of creating a script to do this you could create a pants plugin. The plugin would add a new task which would depend on some product (output of a task) then you should have access to the paths of the generated files you need.

Is anyone familiar with the details of

pants.backend.jvm.tasks.jar_task

and the

JarTool

? According to [1] all content of a dir will be added to the jar .. but when the

JarTool

actually is executed [2], nothing happens Finally, [3] seems to show that

JarTool

is working as expected .. so I wonder what I am missing 💤 [1] https://github.com/pantsbuild/pants/blob/1e45167fab9a30f32207d025d91d2a071c8981fe/src/python/pants/backend/jvm/tasks/jar_task.py#L161-L161 [2] https://github.com/pantsbuild/pants/blob/1e45167fab9a30f32207d025d91d2a071c8981fe/src/python/pants/backend/jvm/tasks/jar_task.py#L361-L361 [3] https://github.com/pantsbuild/pants/blob/664429cb687ec9e81c92cb9c9d48115117d74691/tests/java/org/pantsbuild/tools/jar/JarBuilderTest.java#L422

@purple-oil-45048 : JarTool isn't for direct use, so the questions are better posed as: "i have this BUILD file, but i'm not getting the output i wanted"

@straight-waiter-86090 : the

export

task exports classpaths, but not the node.js resolve directories
