如何在Jenkins流水线Groovy脚本中检测Artifactory触发构建原因？

刚好之前我也折腾过Jenkins里Artifactory插件触发的构建原因检测，结合你已经掌握的其他触发类型的检测逻辑，其实写法非常类似——不过要注意类的包路径，你之前预想的包名不对，Artifactory的触发Cause类不在hudson.triggers下面，而是属于JFrog的专属包。

核心检测代码 #

直接用这段代码就能检测Artifactory插件触发的构建：

// Check if the build was triggered by Artifactory Plugin
artifactoryCause = upStreamBuild.getCause(org.jfrog.hudson.trigger.ArtifactoryTriggerCause)
if (artifactoryCause != null) { 
    return artifactoryCause.getShortDescription() 
}

整合到你的现有逻辑里 #

把上面的代码插入到你已有的检测流程中，完整的示例如下：

//Check if the build was triggered by SCM change
scmCause = upStreamBuild.getCause(hudson.triggers.SCMTrigger.SCMTriggerCause)
if (scmCause != null) { return scmCause.getShortDescription() }

//Check if the build was triggered by timer
timerCause = upStreamBuild.getCause(hudson.triggers.TimerTrigger.TimerTriggerCause)
if (timerCause != null) { return timerCause.getShortDescription() }

//Check if the build was triggered by Artifactory Plugin
artifactoryCause = upStreamBuild.getCause(org.jfrog.hudson.trigger.ArtifactoryTriggerCause)
if (artifactoryCause != null) { 
    return artifactoryCause.getShortDescription() 
}

//Check if the build was triggered by some jenkins project(job)
upstreamcause = upStreamBuild.getCause(hudson.model.Cause.UpstreamCause.class)
if (upstreamcause != null) {
    job = Jenkins.getInstance().getItemByFullName(upstreamcause.getUpstreamProject(), hudson.model.Job.class)
    if (job != null) {
        upstream = job.getBuildByNumber(upstreamcause.getUpstreamBuild())
        if (upstream != null) { return upstream }
    }
}

return;

额外注意点 #

• 确保你的Jenkins已经安装了Artifactory插件，否则这个org.jfrog.hudson.trigger.ArtifactoryTriggerCause类会找不到，导致检测失败。
• 如果是在Pipeline脚本中使用，要确认脚本的权限足够访问这个第三方插件的类，避免出现权限相关的报错。
