Allow the user to set --skip-existing with Twine

[di]

The twine upload command has a --skip-existing flag that allows it to skip (and not exit with an >0 exit code) if it tries to upload a distribution that already exists on PyPI.

Is it possible to configure this action to add that flag to it's twine invocation? If not, can it be added?

Thanks!

LOL I just added it like a few days ago: https://twitter.com/webKnjaZ/status/1275400305581199360.

Added 00ef3b8 6 days ago and today I realized that for my use-case I can set up GHA workflow better so that there's no race conditions.

FWIW

   with:
     skip_existing: true

P.S. I don't recommend running this action from multiple jobs in the same workflow matrix. There's usually a better way to synchronize things like use artifacts upload/download and publish them all together.

Oops! Looks like I didn't RTFM 🙂

@di by the way, feel free to invite me to review GHA workflow PRs if needed.
