Delete Jenkins job workspaces left after renaming

When renaming a job or moving one from slave to slave Jenkins copies it and does not delete the original. This script can fix that.

#!/usr/bin/env python
import urllib, json, os, sys
from shutil import rmtree
 
url = 'http://jenkins/api/python?pretty=true'
 
data =  eval(urllib.urlopen(url).read())
jobnames = []
for job in data['jobs']:
    jobnames.append(job['name'])
 
def clean(path):
  builds = os.listdir(path)
  for build in builds:
    if build not in jobnames:
      build_path = os.path.join(path, build)
      print "removing dir: %s " % build_path
      rmtree(build_path)
 
clean(sys.argv[1])
