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

Answer 1

If you want to clear the build history of MultiBranchProject (e.g. pipeline), go to your Jenkins home page → Manage Jenkins → Script Console and run the following script:

def projectName = "ProjectName"
def project = Jenkins.instance.getItem(projectName)
def jobs = project.getItems().each {
  def job = it
  job.getBuilds().each { it.delete() }
  job.nextBuildNumber = 1
  job.save()
}

Answer 2

If using the Script Console method then try using the following instead to take into account if jobs are being grouped into folder containers.

def jobName = "Your Job Name"
def job = Jenkins.instance.getItemByFullName(jobName)

or

def jobName = "My Folder/Your Job Name
def job = Jenkins.instance.getItemByFullName(jobName)

Answer 3

This one is the best option available.

Jenkins.instance.getAllItems(AbstractProject.class).each {it -> Jenkins.instance.getItemByFullName(it.fullName).builds.findAll { it.number > 0 }.each { it.delete() } }

This code will delete all Jenkins Job build history.

Another easy way to clean builds is by adding the Discard Old Plugin at the end of your jobs. Set a maximum number of builds to save and then run the job again:

Answer 5

You could modify the project configuration temporarily to save only the last 1 build, reload the configuration (which should trash the old builds), then change the configuration setting again to your desired value.

Answer 6

Using Script Console.

In case the jobs are grouped it's possible to either give it a full name with forward slashes:

getItemByFullName("folder_name/job_name") 
job.getBuilds().each { it.delete() }
job.nextBuildNumber = 1
job.save()

or traverse the hierarchy like this:

def folder = Jenkins.instance.getItem("folder_name")
def job = folder.getItem("job_name")
job.getBuilds().each { it.delete() }
job.nextBuildNumber = 1
job.save()
