#23442 uv resolver attempts to use [sources] in uv.toml Issue created by tmarback Describe the bug When using the experimental

uv

lockfile capability (

resolver = "uv"

), if there is an index defined for specific dependencies using

resolves_to_sources

, the current implementation (added in #23322) is to add a

[sources]

block to the generated

uv.toml

file; however, this is not allowed by uv, which only accepts that configuration in `pyproject.toml`, and causes the resolver to throw an error:

Engine traceback:
  in `generate-lockfiles` goal

ProcessExecutionFailure: Process 'Generate uv lockfile for python-default' failed with exit code 2.
stdout:

stderr:
error: Failed to parse: `uv.toml`. The `sources` field is not allowed in a `uv.toml` file. `sources` is only applicable in the context of a project, and should be placed in a `pyproject.toml` file instead.
