我的要求很简单，我只想外部化一些“值”以使我的Jenkinsfile更可重用，为此，我需要从一个文件中加载属性，该文件将紧挨Jenkinsfile，并确保这些属性是在管道中的任何地方都可用。我仍然对groovy和Jenkins代码不熟悉，但是从未想到过如此简单的事情会如此困难。我在脚本安全性插件中启用了一些方法，但是以下代码（以及我尝试过的几种变体）始终会引起错误或显示null或给我NPE。我尝试了多种组合，下面的代码只是其中之一。

properties = null

@NonCPS
def loadProperties() {
    checkout scm
    File propertiesFile = new File('${workspace}/pipeline.properties')
    propertiesFile.withInputStream {
            properties.load(propertiesFile)
    }
}

pipeline {
    agent none

    stages {

        stage ('prepare') {
            agent any

            steps {
                script {
                loadProperties()
                echo "${properties['repo']}"
                }
            }
        }
        stage('Build') {

            agent any

            steps {
                sh 'echo ${properties.repo}'
            }

        }
    }
}

尝试在Jenkins声明性管道脚本中使用cron触发的版本：

options
{
    disableConcurrentBuilds()
    timeout(time: 1, unit: 'HOURS')
    buildDiscarder(logRotator(numToKeepStr: '5'))
    pipelineTriggers([cron('H 0 * * *')])
}

运行时，抛出此异常：

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 30: Invalid option type "pipelineTriggers". Valid option types: [buildDiscarder, catchError, disableConcurrentBuilds, overrideIndexTriggers, retry, script, skipDefaultCheckout, skipStagesAfterUnstable, timeout, timestamps, waitUntil, withContext, withCredentials, withEnv, ws] @ line 30, column 3.
        pipelineTriggers([cron('H 0 * * *')])
     ^
