Due to a misconfiguration, I have over 1700 failed builds in a Jenkins job.
How can I efficiently clean them?

Jenkins provides a plugin called Timestamper that can be used to provide time stamps in your console output. The output will look like this...
21:51:15 Started by user anonymous
21:51:15 Building on master
21:51:17 Finished: SUCCESS
Delete a Jenkins build via GUI.
Go into the build you want to delete, and click the Delete this build button in the upper right corner.
If you need to clean the Jenkins build history, and reset the build number back to 1, you can run a simple script in Jenkins Script Console. source
Go to Jenkins Script Console.
Go to your Jenkins home page -> Manage Jenkins -> Script Console.
Run this script to clean and reset.
Copy and paste this script to your Console Script text area and change the
"copy_folder"to the project name that you need to clean the history. Then click the Run button.def jobName = "copy_folder" def job = Jenkins.instance.getItem(jobName) job.getBuilds().each { it.delete() } job.nextBuildNumber = 1 job.save()If you're using multibranch pipeline or folders, the second line of the above script has to be modified like this:
def jobName = "path/to/your/jenkins/pipeline/master" def job = Jenkins.getInstance().getItemByFullName(jobName, Job.class)
Another way to remove old builds or jobs is from the command-line.
Login to Jenkins command-line.
To remove an entire job and build history remove the job folder, e.g.:
rm -rf jobs/jobname
To look at build history:
$ ls jobs/jobname/builds 1409 1411 1413 1415 1417 1419 1421 1423 1425 923 963 974 985 lastFailedBuild lastSuccessfulBuild lastUnsuccessfulBuild 1191 1334 1348 1379 1381 1383 1406 1408 1410 1412 1414 1416 1418 1420 1422 1424 913 962 973 978 987 lastStableBuild lastUnstableBuild legacyIds
To remove selected builds then remove the build number directory, e.g.:
rm -rf jobs/jobname/builds/97* jobs/jobname/builds/13*
Don't forget the last step if removing or editing files under Jenkins.
After removing jobs or builds from file system you need to go to Manage Jenkins in the Jenkins GUI and click Reload Configuration from Disk.
Note: The Jenkins home directory might be in /var/jenkins_home or /var/lib/jenkins or another location.

You have several options:
Temporarily set the number of builds to keep in the job configuration (Discard Old Builds) so that those builds will be deleted when the next build finishes. If the next build is 1800, set it to keep the most recent 85 or so. Mark all older builds (i.e. 1 to 10) as Keep This Build Forever before starting the next build. This option will fail to delete some builds if you have a downstream job that prevents upstream builds from being deleted (not a problem in your situation if all of them failed though).
Use the Script Console in Manage Jenkins. If it's a top level job (not in a folder), the following will do the trick:
Of course, this approach generally requires good backups. There's a lot you can break using the script console.
Delete the builds' folders from disk (by default in
$JENKINS_HOME/jobs/JobName/builds/, using the start time stamp as folder name) and restart Jenkins, or Reload Configuration From Disk. This option will not allow plugins that e.g. keep the SVN history in order by moving any changes to the subsequent build to do their job.
