Publish NuGet Packages from TeamCity to Azure DevOps Artifacts

Question

I am trying to configure the Azure Artifacts Credential Provider to allow me to connect to Azure DevOps and publish NuGet packages to the Artifacts feed. I have installed the credential provider on my build server. However every time that I run the build I get the following error:

Am I supposed to pass in a PAT to the Credential Provider or is the account that is running the build need to have access to Azure DevOps so that it can generate credentials? The documentation was a little unclear to me about how this works. My TeamCity instance is a little out of date so maybe I need to work on getting that upgraded first.

Answer 1

Please, add NuGet Credentials Provider build feature for your build configuration. Specify an URL for the feed (the same way as you did in NuGet Publish build step), a valid username + PAT (not a password in there).

Answer 2

The accepted answer seems to no longer be working. On TeamCity 2019.1.4 running on Windows Server 2016 and using .NET Core 2.2.105:

[push] WARNING: The credential plugin model used by 'C:\TeamCity\buildAgent\plugins\nuget-agent\bin\credential-provider\CredentialProvider.TeamCity.exe' is deprecated. Please contact the provider of the plugin for an alternative. More information about the recommended plugin model can be found at 'https://aka.ms/nuget-cross-platform-authentication-plugin'.

[17:18:31][push]   Response status code does not indicate success: 401 (Unauthorized).

Manually installing and running the https://github.com/microsoft/artifacts-credprovider works from the command line if I log in to the server and set the env vars for non-interactive use, but does not work within the context of a TeamCity Build job.

Is there a newer TeamCity runner than can handle authentication for dotnet nuget push to Azure Artifacts?
