Outdated solution note ยท pdm-project/pdm
pdm-project/pdm uv backend index credentials command line | pdm-project/pdm github uv.py resolver index_url credential keyring 2025
Older notes for pdm-project__pdm-3555 can help with context, but they do not fully cover the current failure mode.
Why the common answers are incomplete
PDM uv backend resolution loses index credentials when building the uv command line.
Thread PDM index credentials, including keyring-provided credentials, into the uv resolver invocation while redacting secrets from logs.
The relevant code path points at uv.py, resolver index_url, credentials, and keyring, so the patch should sit where PDM translates configured sources into uv CLI arguments.
