Question

Hi,

I want to create a custom powershell task to promote packages uploaded to Azure Artifacts automatically during the build pipeline.

I have successfully created a custom task, but I can't find a way to authenticate my request.

I build the url using the environment variables, which works:

$url = "$($env:SYSTEM_TEAMFOUNDATIONCOLLECTIONURI)_apis/packaging/feeds/$feedName/nuget/packages/" + $pkgName + "/versions/" + $pkgVersion + "?api-version=7.0"

I wanted to authenticate using an Authentication HTTP header build manually using $env:SYSTEM_ACCESSTOKEN and using Invoke-RestMethod but it seems the access token is not available in the scope of the custom task.

How am I supposed to call the Azure DevOps server api from inside a powershell custom task?

I did not find an ewisting task doing the same using powershell.

There seems to exists a Vsts .NET Library wrapper, but I am not sure I can easily PATCH the package version to publish it to a field, and I can not find how I am supposed to import this library.

I have found this issue microsoft/azure-pipelines-task-lib#579 in azure-pipeline-task-lib but for the typescript language. Feel free to move this issue to the other repo if more appropriate.

Hi @tbolon, thank you for your question.
Since this issue is related to the task lib repo and this repo is mostly for pipeline tasks - could you please open the ticket on the https://github.com/microsoft/azure-pipelines-task-lib?
