#20643 fetching python dependencies from a private repository (index) in Artifact Registry Issue created by zaidshennar Describe the bug I'm trying to use a custom repository to load a fork of one of the dependencies following these instructions. I setup Google Artifact Registry as a python repository and I'm linking to it in

pants.toml

with

indexes.add = ["<https://us-central1-python.pkg.dev/{project}/{repo}/simple>"]

. The dependency was then added to the

requirements.txt

file. When running

pants generate-lockfiles

, the repo is correctly added in the pip install step, but it seems like it cannot be found (or auth denied). Pants cannot find and download the packages from this private python repo. Running

pip install

from my linux environment with the specified python repo works successfully. Is there a way to get pants to read the

keyrings.google-artifactregistry-auth

and add it to its environment before downloading the dependencies? Or is there a way to attach permissions before loading dependencies from private repos? Pants version 2.16.1 OS Linux Additional info Add any other information about the problem here, such as attachments or links to gists, if relevant. pantsbuild/pants
