如何加载 Groovy 文件并通过 Jenkins 声明式管道脚本调用其中的方法

Question

I have Jenkinsfile as below in Declarative Pipeline format.

pipeline{
    agent{
        label 'xyz-test'
    }
    options{
        timeout(time: 1, unit: 'HOURS')
        timestamps()
    }
    environment {
        UTILITY = load pwd() + 'path to /utils.groovy'
    }
    stages{
        stage('Build'){
            steps{
                sh "${UTILITY.functionX()}"
            }
        }
    }
}

I have a groovy file with name utils.groovy

def functionX(){
}

def functionY(){
}

return this;

When I call functionX() in such a way, I am getting below error in the console.

hudson.remoting.ProxyException: groovy.lang.MissingMethodException: No signature of method

you need to use 'load' steps from 'Pipeline: Groovy' plugin ( https://plugins.jenkins.io/workflow-cps ) in a script block. ( https://jenkins.io/doc/pipeline/steps/workflow-cps/#-load-evaluate-a-groovy-source-file-into-the-pipeline-script )

ex:

stages {
    stage ("load scripts"){
        steps {
            script {
                scripts=load "jenkins/scripts/loadScripts.groovy"
            }
        }
    }
