uv version --bump major half-fails with incompatible conflicts #14433
Description
Summary
Running uv version --bump major to update the project version "fails" when there are conflicting extras. The update still goes through, but it prints an error and exits with status code 2. The bump (major/minor/patch) doesn't matter.
This was working normally on 0.7.2. It started happening when I upgraded to 0.7.19.
Full example:
❯ cat pyproject.toml
[project]
name = "project"
version = "0.1.0"
requires-python = ">=3.12.0"
dependencies = []
[project.optional-dependencies]
cpu = [
"torch>=2.7.0",
"torchvision>=0.22.0",
]
cu128 = [
"torch>=2.7.0",
"torchvision>=0.22.0",
]
[tool.uv]
conflicts = [
[
{ extra = "cpu" },
{ extra = "cu128" },
],
]

{ index = "pytorch-cpu", extra = "cpu" },
