Jenkins 僵尸任务&排队任务清理

Tools 评论

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）

1
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

1
curl -X POST 'http://jenkins/queue/cancelItem?id=85'

To find x, you can parse the result of:

1
http://jenkins/queue/api/json?tree=items[id,task[name]]

To cancel a build that is in progress:

1
http://jenkins/job/<jobName>/y/stop

To find y, you can parse the result of:

1
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。

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

1

3
Thread.getAllStackTraces().keySet().each() {
  t -> println("name:"+t.getName())
}

进程名字结果示例:

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

3
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()
