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

Deleting directly from file system is not safe. You can run the below script to delete all builds from all jobs ( recursively ).

def numberOfBuildsToKeep = 10
Jenkins.instance.getAllItems(AbstractItem.class).each {
  if( it.class.toString() != "class com.cloudbees.hudson.plugins.folder.Folder" && it.class.toString() != "class org.jenkinsci.plugins.workflow.multibranch.WorkflowMultiBranchProject") {
    println it.name
    builds = it.getBuilds()
    for(int i = numberOfBuildsToKeep; i < builds.size(); i++) {
        builds.get(i).delete()
      println "Deleted" + builds.get(i)
    }
  }
}
