#21688 Resources not available while running a python_source Issue created by thelittlebug link to the example repo: https://github.com/thelittlebug/pants_resources_possible_bug Possible Bug? Feature? Undocumented Behavior? Preamble I’m facing an issue with generated resources and Python. I already discussed this on Slack: Slack thread here. However, as I’ve learned: always create a minimal working project to showcase the issue. So, here we are. What’s Working 1. The generated file is included in the loose layout of the PEX • Command:

pants package ::

• You can inspect the output at

dist/src.python.example/loose.pex/example

, the

generated.txt

is right there. 2. It works in the loose layout of the PEX • Command:

pants run src/python/example:loose

• Output:

found_generated_txt=True

3. It works in the zipapp layout of the PEX • Command:

pants run src/python/example:zipapp

• Output:

found_generated_txt=True

What’s Not Working 1. The generated file is missing when running the

python_sources

target directly. This would be a huge speed boost for Django projects since it avoids waiting for a regenerated PEX file. • Command:

pants run src/python/example/main.py

• Output:

found_generated_txt=False

Questions 1. Is this behavior intended? 2. Is there a workaround? Thanks Thanks to everyone on the team for your hard work on such a massive tool. It gets better with every release. Keep up the great work! 🎉 pantsbuild/pants
