如何处理每晚构建Jenkins声明性管道

Question

我的repo中有一个带有Jenkinsfile的multibranch管道,我可以在每次提交时使用我的CI工作流程(构建和单元测试 - > deploy-dev - >批准 - > deploy-QA - >批准 - > deploy-prod) .我想做的是在第一阶段构建和单元测试的夜间构建中添加SonarQube Analysis.由于我的构建是由Gitlab触发的,我已经定义了我的管道触发器如下:

pipeline {
    ...
    triggers {
        gitlab(triggerOnPush: true, triggerOnMergeRequest: true, branchFilterType: 'All')
    }
    ...
}

为了设置我的夜间构建,我添加了

triggers {
    ...
    cron('H H * * *')
}

但是现在,如果我们只在晚上构建由cron表达式触发的作业,如何执行分析步骤？

我简化的构建阶段如下所示:

stage('Build & Tests & Analysis') {
    // HERE THE BEGIN SONAR ANALYSIS  (to be executed on nightly builds)
    bat 'msbuild.exe ...'
    bat 'mstest.exe ...'
    // HERE THE END SONAR ANALYSIS (to be executed on nightly builds)
}

有如何获取构建触发器信息的方法.这里描述:https: //jenkins.io/doc/pipeline/examples/#get-build-cause

你也可以检查一下: 如何在工作流程中获得$ CAUSE

对您的案例非常好的参考是https://hopstorawpointers.blogspot.com/2016/10/performing-nightly-build-steps-with.html.以下是该来源的功能,完全符合您的需求:

// check if the job was started by a timer
@NonCPS
def isJobStartedByTimer() {
    def startedByTimer = false
    try {
        def buildCauses = currentBuild.rawBuild.getCauses()
        for ( buildCause in buildCauses ) {
            if (buildCause != null) {
                def causeDescription = buildCause.getShortDescription()
                echo "shortDescription: ${causeDescription}"
                if (causeDescription.contains("Started by timer")) {
                    startedByTimer = true
                }
            }
        }
    } catch(theError) {
        echo "Error getting build cause"
    }

    return startedByTimer
}

对我来说，最简单的方法是在构建触发器中定义一个 cron 并使用以下命令验证夜间阶段的时间when expression：

pipeline {
    agent any
    triggers {
        pollSCM('* * * * *') //runs this pipeline on every commit
        cron('30 23 * * *') //run at 23:30:00 
    }

    stages {
        stage('nightly') {
            when {//runs only when the expression evaluates to true
                expression {//will return true when the build runs via cron trigger (also when there is a commit at night between 23:00 and 23:59)
                    return Calendar.instance.get(Calendar.HOUR_OF_DAY) in 23
                }
            }

            steps {
                echo "Running the nightly stage only at night..."
            }
        }
    }
}

这适用于声明性管道

when {
    triggeredBy 'TimerTrigger'
}
