how do I use "nuget push" with the --skip-duplicate option in task DotNetCoreCLI@2

Question

In Azure DevOps, I'd like to use the dotnet core CLI task to push a package with the --skip-duplicate option set. How do I do that?

I tried to set arguments: --skip-duplicate, but that's not getting reflected in the executed command.

I tried custom command with custom: nuget push, but that indicates nuget push isn't a valid custom command.

How do I make the DotNetCorCLI@2 task perform dotnet nuget push <pathspec> --skip-duplicate (with also the --source option set to an internal package source)

Answer 1

Try to use custom: nuget and put the push in argument. Check the following syntax:

steps:
- task: DotNetCoreCLI@2
  displayName: 'dotnet nuget push'
  inputs:
    command: custom
    custom: nuget
    arguments: 'push *.nupkg -s https://pkgs.dev.azure.com/xxxx/_packaging/xxx/nuget/v3/index.json --skip-duplicate'

Answer 2

You should be able to use the nuget authenticate and the nuget push instead of the dotnet core CLI. It has a couple of more features

- task: NuGetAuthenticate@0
  displayName: 'NuGet Authenticate'
- task: NuGetCommand@2
  displayName: 'NuGet push'
  inputs:
    packagesToPush: '$(Build.ArtifactStagingDirectory)/**/*.nupkg'
    command: push
    feedsToUse: 'select'
    publishVstsFeed: 'feedname'
    allowPackageConflicts: true
