How to use import statement in jenkisfile

Question

I am running a groovy script which needs access to two modules jeninks.model and hudson.model

i tried importing these two via import statement in my jenkinsfile but the issue is still there.

Error: groovy.lang.MissingPropertyException: No such property: build for class: groovy.lang.Binding at groovy.lang.Binding.getVariable(Binding.java:63)

Any solution by which i can do this?

The script is working fine when i am using a freestyle job with Execute System Groovy.

import jenkins.model.*
import hudson.model.*

pipeline{
    agent any 
    stages{
        stage('py version'){
            steps{
                bat 'python --version'
            }
        }
        stage('get jobs'){
            get_job()
        }
    }
}


def get_job(){

    def cutOfDate = System.currentTimeMillis() - 1000L * 60 * 60 * 24 * 2

    def filename = build.workspace.toString() + "/jobs_lists.txt"
    targetFile = new File(filename).write("")
    targetFile = new File(filename).append("<table><tr><th>Job Name</th><th>Last Build on</th><th>Keep</th><th>username</th></tr>")
    println "Cut of Date: " + cutOfDate

}

If you just want to access the Workspace DIR you can use the $WORKSPACE environment variable.

Example :

def get_job(){

    def cutOfDate = System.currentTimeMillis() - 1000L * 60 * 60 * 24 * 2
    println("$WORKSPACE")
    def filename = "$WORKSPACE" + "/jobs_lists.txt"
    targetFile = new File(filename).write("")
    targetFile = new File(filename).append("<table><tr><th>Job Name</th><th>Last Build on</th><th>Keep</th><th>username</th></tr>")
    println "Cut of Date: " + cutOfDate

}

If you want to access the current build context use currentBuild which will return a RunWrapper. Example below.

def changeset = currentBuild.changeSets

pipeline {
    agent any

    stages {
        stage('Test') {
            steps {
                script{
                    getJobs()
                }
            }
        }
    }
}


def getJobs() {
    Jenkins.instance.getAllItems(Job.class).each { jobitem ->
          def jobName = jobitem.name
          def jobInfo = Jenkins.instance.getItem(jobName)
          println(jobName)
    }
}
