Hi @adi-khot !
Could you describe the bug and how you solved it this way ?
Was it tested on test pypi ?

[adi-khot]

Hi @CassNot, the bug was in build command. Before we use "python -m build" which uses the setuptools.build_meta driven by pyproject.toml. It does not rely on setup.py.
In the project we use setup.py, so the config is misaligned with package layout, we get failures to create wheel package.
It was tested 2 versions on test pypi with successful creation of source and build distribution.

PR approved on my end. I am letting @mario-valdivia merge as he could be interested in this solution, following our discussion 2 weeks ago !

@adi-khot and @mario-valdivia , I brought a few changes as we had discussed:
Problem 1: we had 2 versioning systems (setup.py uses scmver (scmver=True, setup_requires=["scmver"] and pyproject.toml uses setuptools_scm ([tool.setuptools_scm]))
Proposed solution:

• scmver removed from build requirements
• setuptools_scm is the only versioning backend

Problem 2: pyproject.toml sets package-dir = {"" = "src"}, but src/ does not exist (packages are in merlin/)
Proposed solution:

• package discovery in pyproject.toml is now looking for merlin/ at repo root

I tested these changes on test pypi and the correct tagged version was built.

However, no archive version is built anymore (only the wheel), I think it is because we have python -m build --wheel and not python -m build --sdist --wheel. @mario-valdivia, is there a reason for it ?
