How do I clear my Jenkins/Hudson build history?

Question

I recently updated the configuration of one of my hudson builds. The build history is out of sync. Is there a way to clear my build history?

Please and thank you

Use the script console (Manage Jenkins > Script Console) and something like this script to bulk delete a job's build history https://github.com/jenkinsci/jenkins-scripts/blob/master/scriptler/bulkDeleteBuilds.groovy

That script assumes you want to only delete a range of builds. To delete all builds for a given job, use this (tested):

// change this variable to match the name of the job whose builds you want to delete
def jobName = "Your Job Name"
def job = Jenkins.instance.getItem(jobName)

job.getBuilds().each { it.delete() }
// uncomment these lines to reset the build number to 1:
//job.nextBuildNumber = 1
//job.save()
