Jenkins PipeLinetriggers选项崩溃

Question

尝试在詹金斯声明管道脚本中使用cron触发的构建：

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

运行时，引发此例外：

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 * * *')])

任何人都知道管道脚本中的cron触发器的正确语法或解决方法？

Answer 1

来自jenkins-37731，我看到一个带有以下语法的cron：

properties([
    pipelineTriggers([
        cron('H/5 * * * *')
    ])
])

例如，请参见示例jenkins-infra/jenkins.io/Jenkinsfile。

由于您使用的是声明的管道，因此需要注入这些属性：请参阅" Jenkins声明管道：如何注入属性"

您可以在steps标签内使用script步骤来运行任意管道代码。

那是因为pipelineTriggers和parameters被排除在Job属性中，如pipeline/modeldefinition/model/Options.groovy

所示

public final static List<String> BLOCKED_PROPERTIES = ["pipelineTriggers", "parameters"]

Answer 2

这是您使用管道语法进行操作的方式：

pipeline {
    agent any
    triggers {
        cron('H 4/* 0 0 1-5')
    }
    stages {
        stage('Example') {
            steps {
                echo 'Hello World'
            }
        }
    }
}

此外，PollSCM定义了一个常规间隔，詹金斯应检查新的源更改。如果存在新的更改，则管道将被重新触发。例如：

// every 15 minutes
triggers { 
  pollSCM('H 4/* 0 0 1-5') 
}
