在groovy中列出Jenkins上所有及时触发的工作

Question

我想列出在我的jenkins中及时触发的所有工作。我尝试了下面的代码。

#!/usr/local/bin/groovy

import hudson.model.*
import jenkins.model.*

void log(msg) {
    manager.listener.logger.println(msg)
}

hudson.model.Hudson.instance.getItems().each  { job ->
  def cause = "${job.getPreviousBuild().getCauses()}"
  if (cause =~ "UserIdCause") {
        log("Triggered by user")
    }
  if (cause =~ "TimerTriggerCause") {
        log("Timely triggered Job name:"+ job.getName())
  }
}

它给我以下错误：

Groovy script failed:
groovy.lang.MissingMethodException: No signature of method: hudson.model.FreeStyleProject.getPreviousBuild() is applicable for argument types: () values: []

    at java.lang.reflect.Method.invoke(Method.java:497)

我不知道是什么导致了这个错误。 我已经提到了链接： Jenkins library: java.lang.NullPointerException: Cannot invoke method xxx on null object Jenkins Groovy: What triggered job

做以下修改后做对了：

#!/usr/local/bin/groovy

import hudson.model.*
import jenkins.model.*
import com.cloudbees.hudson.plugins.folder.Folder

void log(msg) {
    manager.listener.logger.println(msg)
}

Jenkins.instance.getAllItems(AbstractProject.class).each  { job ->
    if (job instanceof Folder) {
        log("[i] Folder found:" + job.getName())
    }
    else if(job.getLastBuild())
    {
        def cause = "${job.getLastBuild().getCauses()}"
        if (cause =~ "UserIdCause") {
            log("Job triggered by user: "+job.getName())
        }
        if (cause =~ "TimerTriggerCause") {
            log("Timely triggered Job: "+ job.getName())
        }
    }
}
