I'm curious what you think of this approach @henryiii, and whether this is something Nox should support upstream.

[henryiii]

This seems fine, and I've been considering the proper way to do this upstream; though what I want to do there is to integrate with needs, so sessions could request and install the produced files.

Not really related, but nox-poetry should be able to use the new plugin support, too, by adding this to the top of a user's noxfile:

/// script
dependencies = ["nox", "nox-poetry"]
///

Oh, also, picking the output name out is potentially a bit fragile; wouldn't it be better to use build's API?

That was the initial approach (1dc3bb4) but there were some problems with it:

1. There's no public wrapper around¹

      if (
          self._runner.global_config.no_install
          and self._runner.venv is not None
          and self._runner.venv._reused
      ):
          return None

   that would allow us to skip building the package, so that seems even more fragile than relying on stable output from build.

2. Because we install Poetry into the same venv as nox-poetry for testing, and because Poetry 1.6.1 depends on ^0.10.0², we end up with build being downgraded to a version with an incompatible API. We probably should be installing Poetry in an isolated venv anyway, so this is less of an issue than point 1.
