Is there a way to bulk delete unused jenkins jobs? (not run in the last 6 months)

Question

I have a Jenkins instance with multiple teams using it. It gets cluttered frequently and people don't delete their test jobs after testing. Is there a way to delete unused jobs (not run in the last 6 months) including their workspace?

Answer 1

You can use the following Groovy script for this. Comment out the delete part and test it before using just to make sure it's what you need :)

def deleteBefore = "2022/07/01"

Jenkins.instance.getAllItems(Job.class).each { jobitem ->
  def jobName = jobitem.getFullName()

  def deleteBeforeTime = new Date(deleteBefore).getTime()

  def build = jobitem.getLastBuild() 

  if(build == null || build.getTimeInMillis() <= deleteBeforeTime){ // If no builds, build is null

    println build == null ? "Job " + jobName + " has never run, deleting the Job" : "Job " + jobName + " last ran on (" + build.getTime() + ") hence deleting"
    jobitem.delete()
  }    
}
