Automation scripts for Admins to run on Jenkins Script Console

Jenkins script console is one of the key feature for administrators to automate tasks, troubleshoot on server side like cleaning up older job builds, deleting/creating bunch of jobs, setting up log rotation on all jobs etc. It's hard and monotonous for them to do this tasks from UI repeatedly. The following scripts certainly helps to maintain and operate Jenkins efficiently.

	import jenkins.*
	import hudson.*
	import jenkins.model.Jenkins
	import hudson.model.Job
	import jenkins.model.BuildDiscarderProperty
	import hudson.tasks.LogRotator
	// To delete all older builds of jenkins job provided with limit
	def jobName = "ms-build-job" //Jenkins jobname
	def maxBuildNumber = 33 //Build number, all job builds from starting to maxBuildNumber(Includes) will be deleted
	Jenkins.instance.getItemByFullName(jobName).builds.findAll {
	it.number <= maxBuildNumber
	}.each {
	it.delete()
	}
	//To update next build number for a given job
	Jenkins.instance.getItemByFullName(jobname).updateNextBuildNumber(11)
	//To disable particular job
	def jobName = "Testing/ms-test-job"
	Jenkins.instance.getItemByFullName(jobName).setDisabled(true);
	Jenkins.instance.getItemByFullName(jobName).save();
	//Disable jobs with patterns from all jenkins jobs
	def jobs = Jenkins.instance.getAllItems(Job.class) //Jenkins.instance.getAllItems(AbstractItem.class) -> for listing folder names as well
	jobs.each { job ->
	if(job.fullName.toString().contains("master") && !job.fullName.toString().contains("master/m1") && !job.fullName.toString().contains("master/m2") && !job.fullName.toString().contains("master/m3"))
	{
	println(job.fullName)
	Jenkins.instance.getItemByFullName(job.fullName).setDisabled(true);
	Jenkins.instance.getItemByFullName(job.fullName).save();
	}
	//Add logrotation to all the jenkins jobs
	dryRun = "true" //Modify this to false to apply directly
	daysToKeep = -1
	numToKeep = 50
	artifactDaysToKeep = -1
	artifactNumToKeep = 50
	Jenkins.instance.allItems(Job).each { job ->
	if (job.isBuildable() && job.supportsLogRotator() && job.getProperty(BuildDiscarderProperty) == null) {
	println "Processing \"${job.fullDisplayName}\""
	println "$job.name is updated"
	if (!"true".equals(dryRun))
	{
	job.addProperty(new BuildDiscarderProperty(new LogRotator ( daysToKeep, numToKeep, artifactDaysToKeep, artifactNumToKeep)))
	}
	}
	}
	return;
	};
	//Schedule Jenkins job build from console
	Jenkins.instance.getItemByFullName("Dev/Management").scheduleBuild();
	//Perform logrotation on all jobs, by default logrotation runs after every build. This wil be helpful on non frequently buildings or for the first time when we set logrotation
	Jenkins.instance.getAllItems(Job.class).
	.findAll { it.logRotator }
	.each {
	println it
	it.logRotator.perform(it)
	}
