Duplicate name while building wheel of packages

[I-love-study]

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Windows11
• Poetry version: 1.1.12
• Link of a Gist with the contents of your pyproject.toml file: https://github.com/I-love-study/graiax-silkcoder/blob/6791fe239c3872a6a2c109b3e5ab91245c91c87a/pyproject.toml

Issue

Hello, I try to use poetry to build and publish my packages(which have c extension in it).
But when I try to build wheel. It'll warn me Duplicate name

And when I check the .whl file. I'm surprised that all the .py file have a exactly the same file in it(including name)

I don't know how to solve this problem so I open a issue to ask.
And my package is in here
https://github.com/I-love-study/graiax-silkcoder/blob/6791fe239c3872a6a2c109b3e5ab91245c91c87a

Sorry for my poor English because I'm not a native english speaker.

I cloned that repository at that commit, and poetry build today does not reproduce this problem

[dimbleby]

previous failure to reproduce was likely because I was not on Windows: however this looks like it was #7505 and therefore now has been fixed for real.
