Delete jenkins builds using curl

To delete a single job: 

curl -X POST http://jenkins-user:jenkins-token@hostname:port/job/execute-pipeline/26/doDelete

To delete a range of jobs: 

curl -X POST http://jenkins-user:jenkins-token@hostname:port/job/execute-pipeline/[20-30]/doDelete

This is handy for deleting a build arising from a git event you’ve chosen to ignore in your Jenkinsfile:

def buildId = env.BUILD_ID
node {
    sh "curl -X POST http://my_user:my_token@my_host:8080/job/execute-pipeline/${buildId}/doDelete"
}
