由 Jenkins 管道中的参数化 Cron 触发

问题描述

我有一个像这样的 Jenkins 流水线作业:

I have a Jenkins pipeline job like this:

  triggers {
    parameterizedCron(env.BRANCH_NAME == "master" ? "0 12 * * * % RUN_E2E=true;MODE=parallel" : "")
  }

后来我有这样的条件逻辑:

Later I have conditional logic like this:

    stage('Build Release') {
      when {
        allOf {
          branch 'master'
          not {
            triggeredBy 'TimerTrigger'
          }
        }
      }

但是，triggerBy 没有被激活.即，不是由 timerTrigger 触发的".即使在 parameterizedCron 运行时似乎也是如此.

The triggeredBy is not activated however. That is, "not triggered by timerTrigger" appears to be true even when the parameterizedCron runs.

我从 这里的文档中得到了这个例子.

I got this example from the docs here.

我的问题是，如果我希望我的构建/发布阶段仅在分支 == master 上执行，而在 parameterizedCron 执行期间不，我该怎么做?

My question is, if I want my build/release stage to execute only on branch == master, and not during the parameterizedCron execution, how can I do that?

推荐答案

你的问题是 parameterizedCron 不是 TimerTrigger，只有常规 cron 是.

Your problem is that parameterizedCron is not a TimerTrigger, only the regular cron is.

满足您的要求的最简单方法是添加一个参数并在 parameterizedCron 中设置它:

The easiest way to go about your requirement is to add a parameter and set it in parameterizedCron:

triggers {
    parameterizedCron(env.BRANCH_NAME == "master" ? "0 12 * * * % RUN_E2E=true;MODE=parallel;SHOULD_BUILD_RELEASE=no" : "")
  }

你可以这样做:

    stage('Build Release') {
      when {
        allOf {
          branch 'master'
          expression { SHOULD_BUILD_RELEASE == 'yes' }
        }
      }

否则，您可能会以编程方式发现触发构建的原因，如果发现是 parameterizedCron 触发了构建/发布部分，则退出构建/发布部分.有关示例，请参阅此处.在 parameterizedCron 的情况下，相关部分是这样的:

Otherwise, you may programmatically discover why your build was triggered, and drop out of the build/release part if it turns out that parameterizedCron has triggered it. See here for an example. In the case of parameterizedCron, the relevant part is this:

timerCause = currentBuild.rawBuild.getCause(org.jenkinsci.plugins.parameterizedscheduler.ParameterizedTimerTriggerCause)
if (timerCause) {
    echo "Build reason: Build was started by parameterized timer"
}

最后，您可以尝试使用确切的类，就像这样(我还没有检查过，它可能会或可能不会起作用):

Finally, you may try playing around with the exact class, like this (I haven't checked it and it may or may not work):

    stage('Build Release') {
      when {
        allOf {
          branch 'master'
          not {
            triggeredBy 'ParameterizedTimerTriggerCause'
          }
        }
      }
