bug: using source-dir produces broken SDists

[henryiii]

Description

Using src dir makes broken SDists.

Steps to Reproduce

Use the following minimal pyproject.toml:

[tool.whey]
source-dir = "src"

[build-system]
requires = ["whey"]
build-backend = "whey"

[project]
name = "spam"
version = "0.1.0"

And the following "package":

$ mkdir src
$ mkdir src/spam
$ touch src/spam/__init__.py

Actual result:

Running build:

$ pipx run build

Dies when it tries to make the wheel out of the SDist (requires build 0.5+ with pypa/build#304 )

    raise FileNotFoundError(f"Package directory '{self.config['package']}' not found.")
FileNotFoundError: Package directory 'spam' not found.

Forcing build to build the wheel from the source directly, and not the SDist, works correctly.

$ pipx run build --sdist --wheel

Expected result:

The SDist should not be broken.

Version

• whey: 0.16

Any chance this can get looked at? Producing broken SDists is rather serious (though most users install from wheels). I can't add whey to scikit-hep/cookie unless it produces valid SDists when src folders are present.

Hi @henryiii, sorry for the delay. Can you try with 0.0.17? Should be fixed in that version

[henryiii]

Yes, it works! Thanks!
