Sorry, we've been having issues with the CI. I'm going to close and re-open this to re-trigger it.

For those of you following along, the issue we have is this:

=== NAME  TestIntegration/Integration/PoetryDepOnly/when_building_an_app_with_poetry_dependency_management/creates_a_working_OCI_image_with_a_start_command
    poetry_dep_only_test.go:78:

            import pkg_resources
        ModuleNotFoundError: No module named 'pkg_resources'

We don't feel comfortable releasing the buildpacks until we understand why poetry seems to be failing - and ideally resolved the issue! If anyone has any thoughts please feel free to share, otherwise we'll work on this when we have time.

Hmm, I guess setuptools is either missing or broken

Bummer! I was hoping to play with CNB with my latest project, but this makes it unusable for me.

Any news/progress with this?

Any news/progress with this?

We were able to get the poetry-install tests passing by explicitly including setuptools in the test applications since python 3.12 no longer includes setuptools by default. We will need to evaluate long-term solutions for supporting this new direction for Python, but for now that should get builds passing.

Also includes commit that adds setuptools to test app's pyproject.toml:

If you rely on setuptools or wheel, please make it an explicit dependency in your pyproject.toml.
