使用 Azure DevOps Artifact 时无法在 Build Pipeline 中执行“dotnet tool restore --interactive”

Question

I'm using Azure DevOps and would like to run dotnet tool restore --interactive in my Build Pipeline. In my code repo, there is nuget.config as follows. The file has a private feed hosted in Azure Artifact in addition to nuget.org.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    <add key="MyTools" value="https://mytools.pkgs.visualstudio.com/MyBot/_packaging/MyTools/nuget/v3/index.json" />
  </packageSources>
</configuration>

In the private feed in Azure Artifact, my private dotnet tools exist. To retrieve the tool I created following yml file.

    pool:
      vmImage: "windows-latest"
      demands:
        - msbuild
        - visualstudio
        - vstest
    variables:
      buildPlatform: "Any CPU"
      buildConfiguration: "Release"

    steps:
      - task: PowerShell@2
        inputs:
          targetType: inline
          script: "Invoke-WebRequest -Uri https://raw.githubusercontent.com/Microsoft/artifacts-credprovider/master/helpers/installcredprovider.ps1 -OutFile ./installcredprovider.ps1 ;./installcredprovider.ps1;"
      - task: DotNetCoreCLI@2
        displayName: "Restore tools"
        inputs:
          command: custom
          custom: tool
          arguments: restore --interactive

However, as I run the yml file in the build process, following result appears. As the message shows, it requires sign-in, but I do not want to do device sign-in every time. So Is there any good way so that I do not have to do device log-in every time?

Info: Azure Pipelines hosted agents have been updated to contain .Net Core 3.x SDK/Runtime along with 2.2 & 2.1. Unless you have locked down a SDK version for your project(s), 3.x SDK might be picked up which might have breaking behavior as compared to previous versions. 
Some commonly encountered changes are: 
If you're using `Publish` command with -o or --Output argument, you will see that the output folder is now being created at root directory rather than Project File's directory.

Fail to execute “dotnet tool restore --interactive” in Build Pipeline when using Azure DevOps Artifact

You could not use the command line dotnet tool restore --interactive on the hosted agent, that because:

Microsoft decided not to put the plugin artifacts-credprovider in dotnet.exe because there were concerns that shipping auth integration to Azure DevOps within the sdk would've been unfair to other feed providers. To resolve your 401 issues you need to install the auth plugin manually.

That the reason why you get the 401 (Unauthorized) error.

In addition , you mentioned that you do not want to commit the token info in the nuget.config file, as a solution for this issue, you could add a nuget Service connections with PAT:

Then use this externalFeedCredentials: nugettest in the dotnet restore task instead of powershell task (there is no option to accept the certification Information):

- task: DotNetCoreCLI@2
  displayName: Restore
  inputs:
    command: restore
    projects: path/to/xxx.csproj
    feedsToUse: config
    nugetConfigPath: path/to/NuGet.Config
    externalFeedCredentials: nugettest

Then we could resoter the package from our private feed.

If you get the 403 403 (Forbidden) error with above method, you can check the thread here.

Hope this helps.

Answer 2

You can't use the flag --interactive in a build pipeline, because this flag except to get an output from the user during the execution.

You can use the default restore option in the .Net core task:

- task: DotNetCoreCLI@2
  inputs:
    command: 'restore'
    projects: '$(Build.SourcesDirecotry)/path/to/csproj'
    feedToUse: 'config'
    nugetConfigPath: '$(Build.SourcesDirectory)/path/to/nuget.config'

Answer 3

This one is because you should let agent know the nuget sources with pre-authenticated feed url prior to dotnet restore:

- task: NuGetCommand@2
  displayName: 'Add Nuget Feed'
  inputs:
  command: custom
  arguments: 'sources add -name <name_of_source> -source <feed_url>'

I hope this would be useful.
