I am using a Jenkins declarative pipeline with a Docker agent (Windows label). In my pipeline, I want to get the current git tag for the commit being built, so I can use it for artifact naming.

My checkout stage looks like this:(i tried both)

first way

stage('Checkout') {
      steps {
        checkout scm 
      }
    }

second way

stage('Checkout') {
      steps {
        checkout(
          extensions: [
              [$class: 'CloneOption', depth: 1, shallow: true]
          ]
          )
      }
    }

After this, I run the following PowerShell command to get the tag:

$tag = git -C "$env:WORKSPACE" tag --points-at HEAD | Select-Object -First 1
if ([string]::IsNullOrEmpty($tag)) {
    $tag = "notag"
}

Even though the commit is tagged in the repository, $tag is always empty ("notag"). I have tried both default and shallow clone checkouts, but Jenkins does not seem to fetch tags.

How can I make Jenkins fetch git tags so that git tag --points-at HEAD works in my pipeline? Is there a recommended way to ensure tags are available after checkout?
