Jenkins Pipeline Job with file parameter

Question

I\'m putting together a Jenkins pipeline job which will take a file parameter. I can trigger the job and point it at a file however I can\'t find where the file has ended up

To handle an optional file parameter in pipeline (to handle the use case where no file should be accepted) you could use jenkinsci-unstashParam-library (add it in Jenkins>Manage Jenkins>Configure System>Global Pipeline Libraries https://github.com/janvrany/jenkinsci-unstashParam-library) with a try/catch in a script as this sample stage:

    stage('upload') {
            steps {
                // delete workspace
                cleanWs()

                // handle file parameters in pipeline (JENKINS-27413)
                script {

                    try {
                        // force workspace directory creation
                        sh "touch emptyFileToCreateWorkspace"

                        // https://stackoverflow.com/questions/59468464/fetching-uploaded-files-in-jenkins
                        def file_in_workspace = unstashParam 'MY_FILE.xlsx'

                        // https://unix.stackexchange.com/questions/125776/error-with-a-file-name-containing-parentheses
                        sh "mv '${file_in_workspace}' MY_FILE.xlsx"
                    }
                    catch (Exception e) {
                        echo e.getMessage()
                        echo "No file parameter, we will continue.."
                    }
                }
            }
        }
