如何使用 Jenkins 管道签出特定的标签/提交（git）

Question

till now I ran the follwoing command in jenkins:

git branch: branch_nam, url: url, credentialsId: cred

and it works fine. I've tried to add a way to checkout specific tag/commit so I've used the follwing command:

checkout scm: [$class: 'GitSCM', userRemoteConfigs: [[url: url]], branches: [[name: tag]]], credentialsId: cred, poll: false

but I get the following error:

ERROR: Error cloning remote repo 'origin' hudson.plugins.git.GitException: Command "git fetch --tags --progress http://codefront:8080/tfs/DefaultCollection/some_folder +refs/heads/ :refs/remotes/origin/ " returned status code 128: stdout: stderr: fatal: Authentication failed for http://codefront:8080/tfs/DefaultCollection/some_folder

what did I do wrong? what is the difference between they way each command works?

Thanks in advance

refer to the doc here : https://jenkins.io/doc/pipeline/steps/workflow-scm-step/

check if your url respect it. Please give me the value if it isn't the problem.
