Jenkins PipelineTriggers选项崩溃

Question

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 * * *')])
     ^

有谁知道管道脚本中cron触发器的正确​​语法或解决方法？

Answer 1

从JENKINS-37731，我看到一个cron使用以下语法：

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

例如参见jenkins-infra/jenkins.io/Jenkinsfile。

由于您使用的是声明性管道，因此需要注入这些属性：请参阅“ Jenkins声明性管道：如何注入属性 ”。

您可以使用标记script内的步骤steps来运行任意管道代码。

这是因为pipelineTriggers和parameters被排除在工作属性之外，如pipeline/modeldefinition/model/Options.groovy

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