uv_build cannot find stubs-only package #13546
Description
Summary
in my pyproject.toml I have something like
[project]
name = "numpy-stubs"
# --snip--
[build-system]
requires = ["uv_build>=0.7.5,<0.8"]
build-backend = "uv_build"
# --snip--then I run uv build, and see
Building source distribution...
Error: Missing module directory for `numpy_stubs` in `src`. Found: `numpy-stubs`, `numtype`, `_numtype`
× Failed to build `/home/joren/Workspace/numtype`
├─▶ The build backend returned an error
╰─▶ Call to `uv_build.build_sdist` failed (exit status: 1)
hint: This usually indicates a problem with the package or the build environment.
I also tried
[tool.uv.build-backend]
module-name = "numpy-stubs"but uv build then says
Building source distribution...
× Failed to build `/home/joren/Workspace/numtype`
├─▶ Failed to parse: `pyproject.toml`
╰─▶ TOML parse error at line 7, column 15

Invalid character `-` at position 6 for identifier `numpy-stubs`, expected an underscore or an alphanumeric character
For what it's worth; here's the pyproject.toml source:
