pyproject.toml PEP 621

[cotsuka]

Upstreaming this report. I maintain a PKGBUILD for the AUR and received a bug report from a user.

waveplate [1] added the following comment to python-llm [2]:

ValueError: invalid pyproject.toml config: `project.license`.
configuration error: `project.license` must be valid exactly by one
definition (2 matches found):

    - keys:
        'file': {type: string}
      required: ['file']
    - keys:
        'text': {type: string}
      required: ['text']


ERROR Backend subprocess exited when trying to invoke
get_requires_for_build_wheel
==> ERROR: A failure occurred in build().

I got this error with both the python-condense-json and python-llm packages

license = "Apache-2.0" is the offending line in pyproject.toml

Since the decision was made to strictly enforce PEP 621, the only valid formats are:

license = { text = "Apache-2.0" }

and

license = { file = "LICENSE" }
