Unable to publish to Azure Artifacts

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Windows 10
• Poetry version: 1.0.9
• Link of a Gist with the contents of your pyproject.toml file: Sorry private repo 👍

Issue

I am trying to publish a python package to my companies Azure DevOps Artifacts. I have built the package using poetry. A run the following at the command line:

❯ poetry --version
Poetry version 1.0.9                                                        
❯ poetry config repositories.azure https://pkgs.dev.azure.com/.../pypi/upload
❯ poetry install

I have used Poetry to publish to public repos before. But not Azure or private repos. I have a hunch there may be an issue with Azure Artifacts keyring. The Azure documentation suggests to use twine, and you authenticate with the Azure keyring.

Lastly I tried to copy the code from https://www.nuomiphp.com/eplan/en/104789.html, but I was met with the same error when following this template.

Any ideas on how to publish to Azure Artifacts?

Start with poetry/console/commands/publish.py and poetry/masonry/publishing/publisher.py, then follow the _upload entry point in poetry/masonry/publishing/uploader.py. Reproduce the Azure Artifacts publish command with debug output and inspect how the configured repository and credentials are passed. Done means publishing to the reported Azure endpoint succeeds without the HTTP 401 error.
