Jenkins 僵尸任务&排队任务清理

通过API清理排队的任务

删除已经开始构建的任务（已有build_number）

curl -X POST <jenkins-server>/job/<job-name>/<build-number>/doDelete

对于排队中的任务

注意下面的id 不是build_number

curl -X POST 'http://jenkins/queue/cancelItem?id=85'

To find x, you can parse the result of:

http://jenkins/queue/api/json?tree=items[id,task[name]]

To cancel a build that is in progress:

http://jenkins/job/<jobName>/y/stop

To find y, you can parse the result of:

http://jenkins/job/<jobName>/lastBuild/api/json?tree=building,number

脚本处理排队中的任务

获取jenkins所有排队中任务，然后通过jobname过滤，然后想精确到某个任务可以在任务里通过判断任务的参数来确定：比如唯一的ID。

fun JenkinsServer.cancelTaskInQueue(jobName: String, p1: String, p2: String, p3: String){
    runScript(runScriptHtml(jobName, URLEncoder.encode("import hudson.model.*\n" +
            " \n" +
            "def q = Jenkins.instance.queue\n" +
            "q.items.findAll { \n" +
            "  \n" +
            "  it.task.name.startsWith(\"${jobName}\")\n" +
            "  \n" +
            "}.each { \n" +
            "  p1=\"\"\n" +
            "  p2=\"\"\n" +
            "  p3=\"\"\n" +
            "  it.params.eachLine{\n" +
            "    aa = it.split(\"=\")\n" +
            "    \n" +
            "    if(aa[0].equals(\"p1\")){\n" +
            "      if(aa.length == 2){\n" +
            "      \tp1 = aa[1]\n" +
            "      }\n" +
            "    }\n" +
            "    if(aa[0].equals(\"p2\")){\n" +
            "      if(aa.length == 2){\n" +
            "      \tp2 = aa[1]\n" +
            "      }\n" +
            "    }\n" +
            "    if(aa[0].equals(\"p3\")){\n" +
            "      if(aa.length == 2){\n" +
            "      \tp3 = aa[1]\n" +
            "      }\n" +
            "    }\n" +
            "  }\n" +
            "  if(\"${p1}\".equals(p1) && \"${p2}\".equals(p2) && \"${p3}\".equals(p3)){\n" +
            "    println(\"cancel auto build ${p1}:${p2} is ${p3}\")\n" +
            "    q.cancel(it);\n" +
            "  }\n" +
            "}\n" +
            "\n", "UTF-8")))
}

清除段时间内大量堆积的任务

进入 Manage Jenkins -> Script Console , 然后执行后面的脚本

单条结束任务

查看进程的名字

Thread.getAllStackTraces().keySet().each() {
  t -> println("name:"+t.getName())
}

进程名字结果示例:

name:Thread-90
name:Scheduler-174573182-1
name:Thread-116
name:Thread-110
name:Thread-83
name:org.jenkinsci.plugins.workflow.steps.SynchronousNonBlockingStepExecution [#52]
name:SCMTrigger [#10]

停止特定进程

Thread.getAllStackTraces().keySet().each() {
  t -> if (t.getName()=="刚才查出来的某条进程名字" ) {   t.interrupt();  }
}

删掉所有进程

Thread.getAllStackTraces().keySet().each() {
  t ->   t.interrupt(); 
}

清掉所有Build Queue

Jenkins.instance.queue.clear()
