Checkout a tag in Jenkins pipeline

Question

Tried using

checkout scm: [$class: 'GitSCM', 
  userRemoteConfigs: [[url: '${repoURL}']], 
  branches: [[name: 'refs/tags/${tag-version}']]],poll: false

This fails with an Authentication error. Is there any way other than using

withCredentials

to checkout tag in a Jenkinsfile

After spending, hours got here

Correct way to use GitSCM in declarative pipeline is

checkout scm: [$class: 'GitSCM', userRemoteConfigs: [[url: repoURL, credentialsId: credential]], branches: [[name: tag-version]]],poll: false

Not like I found in most places in web

checkout scm: [$class: 'GitSCM', userRemoteConfigs: [[url: repoURL], [credentialsId: credential]], branches: [[name: tag-version]]],poll: false
