bug: incorrect metadata license file

[b-kamphorst]

Hi! It appears that the formulaic wheel metadata is faulty for the license file. It states License-File: LICENSE, but the license file is located in licenses/LICENSE. As a result, e.g. pip-licenses is unable to determine the license:

# pip-licenses -p formulaic
 Name       Version  License 
 formulaic  0.5.2    UNKNOWN 

The metadata was fine for version 0.4.0:

# pip-licenses -p formulaic
 Name       Version  License     
 formulaic  0.4.0    MIT License 

As such, I expect that this is an issue in the hatching back-end that you migrated to in 0.5.0. However, I'm not familiar with that so I'll leave the assessment and possible propagation to the community.

Hi!

Thanks for reporting this. I checked with hatch upstream, and it looks like they have adopted PEP 639 pre-emptively, which defines this behavior concretely (vs implicitly as before).

If you are using pip-licenses, I'd suggest raising an issue with them, and see if they might not add support for this.

Closing this one out.

Hi @matthewwardrop thank you so much for looking into this and providing a clear answer! I've reported this back to pip-licenses so that they can improve their tool.
