Issue Description

I am building a solution in a pipeline which uses dotnet restore to restore nugets.

After adding a private Azure DevOps feed to nuget.config, it did not work, because the task used a "temporary" nuget.config file.

Adding a vstsFeed to the task did not work, because Centralized Package Management requires source mapping.

Changing the task to use config rather than select does not work because it adds a "feed-" prefix to the feed key, which I cannot do in the source mapping or it will break for developers.

As a workaround, I added an extra DevOps-Nuget.Config where the key just "private" in the source list, but "feed-private" in the source mapping section.

Hi,

I got the same error:

PackageSourceMapping is enabled, the following source(s) were not considered: NugetFoundation, DevExpress.

In my case NugetFoundation is my private nuget repository.

Is there any workarond?

[mortenn]

Yes, the workaround is detailed above;

As a workaround, I added an extra DevOps-Nuget.Config where the key just "private" in the source list, but "feed-private" in the source mapping section.

I did not include the pipeline change to do this, though, so here you go:

  - task: DotNetCoreCLI@2
    displayName: 'Restore NuGet packages'
    inputs:
      command: 'restore'
      feedsToUse: 'config'
      nugetConfigPath: 'DevOps-Nuget.Config'
