Jenkins: Is there any way to cleanup Jenkins workspace?

Question

How can I cleanup the workspace in Jenkins? I am using AccuRev as version control tool.

I created freestyle projects in Jenkins.

not allowed to comment, therefore:

The answer from Upen works just fine, but not if you have Jenkins Pipeline Jobs mixed with Freestyle Jobs. There is no such Method as DoWipeWorkspace on Pipeline Jobs. So I modified the Script in order to skip those:

import hudson.model.*
import org.jenkinsci.plugins.workflow.job.WorkflowJob

// For each project
for(item in Hudson.instance.items) {
  // check that job is not building
  if(!item.isBuilding() && !(item instanceof WorkflowJob))
  {
    println("Wiping out workspace of job "+item.name)
    item.doDoWipeOutWorkspace()
  }
  else {
    println("Skipping job "+item.name+", currently building")
  }
}

you could also filter by Job Names if required: item.getDisplayName().toLowerCase().contains("release")
