hudson CI: how to delete all jobs?

Q: I have about 100 jobs on my hudson CI, possible to mass delete them ?

A: The easiest way, IMHO, would be to use script. Go to http://your.hudson.url/script/

Delete jobs by running in Older versions(1.x):

for(j in hudson.model.Hudson.theInstance.getProjects()) {

j.delete\(\);

}

And this way gives you an option to easily use condition to filter out jobs to delete.

FOR JENKINS Current versions (2.x):

for(j in jenkins.model.Jenkins.theInstance.getAllItems()) {

j.delete\(\)

}

Q: How to reset build number in jenkins?

A: Can be easier done from groovy script console . Go to http://your-jenkins-server/script In script window enter:

item = Jenkins.instance.getItemByFullName("your-job-name-here")

//THIS WILL REMOVE ALL BUILD HISTORY

item.builds.each() { build ->

build.delete()

}

item.updateNextBuildNumber(1)

OR

echo "deleting all builds of ${jobName}" item = Jenkins.instance.getItemByFullName("${jobName}") for (build in item.builds){ build.delete(); } item.updateNextBuildNumber(1)

For ALL PROJECTS

Jenkins.instance.allItems.each() {

item -> item.builds.each() {

build -> build.delete\(\)

}

item.updateNextBuildNumber(1)

}
