Response status code does not indicate success: 409 Conflict - The feed already contains

Question

I am changing my Azure DevOps build to .NET Core.

It's all working except the final push step to get the package in my feed, I get this error:

Response status code does not indicate success: 409 (Conflict - The feed already contains 'mypackage 1.0.x' (Devops Activity ID: xxx))

In the old "Nuget Push" step there was an option to "Allow duplicates to be skipped", specifically to get around this problem - but this option is not available in the "dotnet push" step.

How can this be achieved in the dotnet core world?

Answer 1

This can be accomplished by dividing the process into Build and Release, because the the job in the release pipeline support skipping upload if a package with the same name and version already exists.

Build pipeline

Add a build with the following steps Publish the compiled nupkg file as output of the build.

Release pipeline

Create a release pipeline connected to the build pipeline. Click Alow duplicated to be skipped.
