The uv lock --check command fails even though it should pass.

[yshiftanlightricks]

Summary

The problem is that after running uv lock, the --check command still fails.

the pyproject.toml content is:

[project]
name = "uv_bug"
version = "0.1.0"
requires-python = ">=3.10,<3.11"

[tool.uv]
conflicts = [
  [
    { group = "numpy" },
    { group = "numpy_old" },
  ]
]


[dependency-groups]
numpy = [
  "numpy==2.0.0",
]
numpy_old = [
  "numpy<2.0.0",
]
include_numpy = [
  {include-group = "numpy"},
]

Thank you for the minimal example!

CC @BurntSushi @charliermarsh there's a difference in is_inferred_conflict with include-group:

Conflicts([ConflictSet { set: {ConflictItem { package: PackageName("uv-bug"), kind: Group(GroupName("numpy")) }, ConflictItem { package: PackageName("uv-bug"), kind: Group(GroupName("numpy-old")) }}, is_inferred_conflict: false }, ConflictSet { set: {ConflictItem { package: PackageName("uv-bug"), kind: Group(GroupName("include-numpy")) }, ConflictItem { package: PackageName("uv-bug"), kind: Group(GroupName("numpy-old")) }}, is_inferred_conflict: true }])

Conflicts([ConflictSet { set: {ConflictItem { package: PackageName("uv-bug"), kind: Group(GroupName("numpy")) }, ConflictItem { package: PackageName("uv-bug"), kind: Group(GroupName("numpy-old")) }}, is_inferred_conflict: false }, ConflictSet { set: {ConflictItem { package: PackageName("uv-bug"), kind: Group(GroupName("include-numpy")) }, ConflictItem { package: PackageName("uv-bug"), kind: Group(GroupName("numpy-old")) }}, is_inferred_conflict: false }])

Possibly related to #12005

Presumably the problem is that in the lockfile we store the resolved group

version = 1
revision = 3
requires-python = "==3.10.*"
conflicts = [[
    { package = "uv-bug", group = "numpy" },
    { package = "uv-bug", group = "numpy-old" },
], [
    { package = "uv-bug", group = "include-numpy" },
    { package = "uv-bug", group = "numpy-old" },
]]
