Is build-constraint-dependencies working in uv 0.10.8? #18283
Description
I am attempting to use build-constraint-dependencies with the uv 0.10.8 and python 2.14 on Ubuntu 24.04 which does not seem to work. Below is the test pyproject.toml:
[build-system]
requires = ["setuptools"]
build-backend = "setuptools.build_meta"
[project]
name = "Test"
version = "0.0.1"
[tool.uv]
build-constraint-dependencies = ["setuptools==81.0.0"]
I was expecting that uv build --all will recognize the constrain, but it did not:
$ uv build --all -v 2>&1 | grep setuptools==
DEBUG Selecting: setuptools==82.0.0 [compatible] (setuptools-82.0.0-py3-none-any.whl)
The build time --build-constraints option works as I was expecting constraining the package version:
$ uv build --all -v --build-constraints <(echo "setuptools==81.0.0") 2>&1 | grep setuptools==
DEBUG Selecting: setuptools==81.0.0 [compatible] (setuptools-81.0.0-py3-none-any.whl)
Is build-constraint-dependencies working in uv 0.10.8 or I don't understand how the mechanism should be used?
