6.8.0: pytest is failing in tests/test_api.py::APITests::test_prefix_not_matched` unit about importlib_metadata

[mtelka]

The test failed because you have the pkg package installed:

pkg                           0.0.0

Where this package comes from?

I'm closing this as the issue appears to be an unexpected pkg package in the environment. I quickly scanned through the test fixtures and I don't think they're responsible for creating the pkg package. Next step is to investigate why that's happening and possibly prevent it from happening. Feel free to comment if there's something this project could potentially do differently.

Trying to retest that found that in case of create some directory in project tree (in this case created by rpm) before start build it fails because because some bits are missing in pyproject.toml

* Getting build dependencies for wheel...
error: Multiple top-level packages discovered in a flat-layout: ['SPECPARTS', 'importlib_metadata'].

To avoid accidental inclusion of unwanted files or directories,
setuptools will not proceed with this build.

If you are trying to create a single distribution with multiple packages
on purpose, you should not rely on automatic discovery.
Instead, consider the following options:

1. set up custom discovery (`find` directive with `include` or `exclude`)
2. use a `src-layout`
3. explicitly set `py_modules` or `packages` with a list of names

To find more information, look for "package discovery" on setuptools docs.
