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

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

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?

Solution

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()
  }    
}
