It's said here, https://jenkins.io/doc/pipeline/steps/workflow-basic-steps/#code-dir-code-change-current-directory

Change current directory. Any step inside the dir block will use this directory as current and any relative path will use it as base path.

However, I can't seem to get it work. I use declarative syntax with a very basic Jenkinsfile

pipeline {
    agent none

    stages {

        stage('Change working directory...') {
            agent { docker 'my-image' }

            steps {
                dir('new-dir') {
                    sh 'pwd'
                }
            }
        }
    }
}

What it does is simply create a new folder called "new-dir" in the current working directory and then the pwd prints out the current working directory instead of navigating into the "new-dir".

Am I misusing this step because I can't find many examples online. I have found some relevant issues here, but none of them is of any help to me.
