How to invoke an Azure Devops task from PowerShell script?

Question

I have a number of subfolders in a repository that all contain an Azure ARM template (folder name = resource group).

I'm trying to iterate each folder and then create a pipeline artifact from contents of that folder.

How do I invoke a devops task from PowerShell script? The script below gives an error saying that PublishPipelineArtifact task is not found.

foreach ($folder in (Get-ChildItem -Path $env:SYSTEM_DEFAULTWORKINGDIRECTORY -Directory -ErrorAction SilentlyContinue | Select-Object Name))
{
    Write-Host "Processing folder $($folder.Name)..."

    Write-Host "##vso[task.PublishPipelineArtifact targetPath=$folder;artifactName=$($folder.Name);]"

    Write-Host "Published artifact $($folder.Name)..."
}

I found out that it's possible with "Logging commands". See https://github.com/Microsoft/azure-pipelines-tasks/blob/master/docs/authoring/commands.md

For example this script packages all folders as artifacts:

Write-Host ("Working folder is {0}" -f $($env:SYSTEM_DEFAULTWORKINGDIRECTORY))

foreach ($folder in (Get-ChildItem -Path $env:SYSTEM_DEFAULTWORKINGDIRECTORY -Directory -ErrorAction SilentlyContinue | Select-Object Name))
{
    Write-Host "Processing folder $($folder.Name)..."

    $folderPath = $env:SYSTEM_DEFAULTWORKINGDIRECTORY + "\" + $folder.Name
    $artifactFolder = $env:BUILD_ARTIFACTSTAGINGDIRECTORY + "\" + $folder.Name
    $pathToZip = $artifactFolder + "\" + $folder.Name + ".zip"

    Write-Host "Creating archive to " + $artifactFolder

    New-Item -ItemType directory -Path $artifactFolder

    $compress = @{
        Path = $($folderPath) + "\*"
        CompressionLevel = "Fastest"
        DestinationPath = $pathToZip
    }
    Compress-Archive @compress

    Write-Host "##vso[artifact.upload containerfolder=$($folder.Name);artifactname=$($folder.Name)_drop;]$pathToZip"

    Write-Host "Published artifact $($folder.Name)..."
}
