hatch-build-scripts: do not copy artifacts

[angelo-peronio]

I hope this is the correct place to discuss hatch-build-scripts. I was surprised when I landed here from its New Issue page.

I am trying to use hatch-build-scripts to compile Kaitai Struct format definitions into Python modules. In my case, the format definitions are in src/foo/formats, and I would like to have the resulting Python modules in the same folder.

I tried the following in my pyproject.toml:

[[tool.hatch.build.hooks.build-scripts.scripts]]
work_dir = "src/foo/formats"
out_dir = "src/foo/formats"
commands = [
    "kaitai-struct-compiler.bat --verbose=file --target=python --python-package=. *.ksy",
]
artifacts = ["*.py"]
clean_artifacts = false

python -m build --wheel generates the Python modules in src/foo/formats as expected, but fails to copy them, since they already are where they should be.

What am I missing?
