Example of parsing out the artifacts of the last successful build on Jenkins/Hudson using the JSON api

jenkinsBuildArtifacts.groovy

import groovy.json.*
def HOSTNAME = 'http://ci.jruby.org'
def JOBNAME = 'jruby-dist'
def JOB_URL = "$HOSTNAME/job/$JOBNAME/lastSuccessfulBuild"
def text = "$JOB_URL/api/json".toURL().text
println JsonOutput.prettyPrint(text)
def json = new JsonSlurper().parseText(text)
json.artifacts.each{
    println it
}
