Question

how to cancel build queue jobs in jenkins through REST API, which are not started by jenkins and are in its build queue. I know how to cancel the in-progress job with below command

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

Answer 1

To cancel a job in the queue, you can POST:

http://jenkins/queue/cancelItem?id=x

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

Answer 2

无法通过其内部编号取消作业，只能通过作业ID：

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