您可以使用以下脚本终止无法找到具有所提供标签的代理的作业。

Jenkins.instance.getAllItems(Job.class).each { job ->
      job.getBuilds().each { b ->        
        if(b.isInProgress()) {
           if(b.getLog().contains("There are no nodes with the label")){
                println "Build: " + b.getNumber() + " of Job: " +  job.getName() + " is Waiting. Hence Killing!!!"
                b.doKill()
           }
        } 
   }  
}
