Credentials for additional indexes configured with PDM are not passed to uv #3553
Description
Describe the bug
I have several indexes configured with PDM in the global config file (~/.config/pdm/config.toml). One is a mirror for PyPI, the others are additional internal indexes. All indexes require authentication.
When using uv with PDM (PDM_USE_UV = True), all the indexes are passed to uv on the command line but without the credentials which obviously causes operations trying to access these indexes to fail.
To reproduce
- Use latest PDM (tested with 2.25.0) and also install uv (tested with 0.7.13)
- Configure an index with PDM that requires authentication in ~/.config/pdm/config.toml
- Create a new empty project (
pdm init) and configure it to use uv (pdm config -l use_uv true) - Try to install a dependency that is only available on the the private index
- The installation fails with the following message: "No solution found when resolving dependencies: Because was not found in the package registry and your project depends on , we can conclude that your project's requirements are unsatisfiable."
At the moment I can work around this issue, by providing a uv config (~/.config/uv/uv.conf) that repeats the indexes configured with PDM.
Expected Behavior
Ideally, PDM would pass the credentials for its configured indexes to uv when it is called under the hood.
