A Groovy Continuous Integration (Jenkins) Dashboard

I took inspiration from this post, but I wanted to use Groovy. I know there are plugins that do the same, but this was intended to be a learning exercise.

Whilst the example in the link is quite simple - I also need to address authentication of the user. Once available this would be used for displaying build status via a wall mounted monitor.

Requires "commons-codec-1.8.jar" and "commons-httpclient-3.1.jar" on the classpath

	import org.apache.commons.httpclient.*
	import org.apache.commons.httpclient.auth.*
	import org.apache.commons.httpclient.methods.*
	import groovy.xml.MarkupBuilder
	def server = "localhost"
	def port = 8093
	def jenkinsHost = "https://${server}:${port}"
	def username = "yourUsername"
	def apiToken = "yourPassword"
	def client = new HttpClient()
	client.state.setCredentials(
	new AuthScope( server, port, "realm"),
	new UsernamePasswordCredentials( username, apiToken )
	)
	// Jenkins does not do any authentication negotiation,
	// ie. it does not return a 401 (Unauthorized)
	// but immediately a 403 (Forbidden)
	client.params.authenticationPreemptive = true
	def post = new PostMethod( "${jenkinsHost}/rssLatest" )
	post.doAuthentication = true
	File file = new File("rssLatest.xml")
	try {
	int result = client.executeMethod(post)
	file.write(post.getResponseBodyAsString())
	} finally {
	post.releaseConnection()
	}
	def builds = new XmlParser().parse("rssLatest.xml")
	def writer = new StringWriter()
	def html = new MarkupBuilder(writer)
	def cssClass
	def hrefURL
	html.html {
	head {
	title 'Continuous Integration HUD'
	style(type: 'text/css', """
	.stable { background-color: green }
	.unstable { background-color: yellow }
	.broken { background-color: red }
	table { margin: 0 auto; }
	a { font-size: bigger; text-decoration: none; color: black; }"""
	)
	script (src: "http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js")
	script (type: "text/javascript", """
	\\\$(document).ready(redraw);
	\\\$(window).resize(redraw);
	function redraw() {
	\\\$('tr').height((\\\$(window).height()-60)/\\\$('tr').size());

	}
	"""
	)
	}
	body{
	table {
	tr {
	def counter = 0
	builds.each{ item->
	cssClass = (item.title.text() =~ 'unstable') ? 'unstable' : 'stable'
	cssClass = (item.title.text() =~ 'broken') ? 'broken' : cssClass
	item.link.each{ a ->
	hrefURL = a.attribute("href")
	}
	td(class: cssClass){
	a(href: hrefURL, item.title.text())
	}
	counter++
	if(counter == 6){
	tr{}
	counter = 0
	}
	}
	}
	}
	}
	}
	println writer
