Update: So many people seem to keep coming to this blog post from Mike Clark's blog that I feel it might make sense to mention that the WeblogPublisher has been incorporated into the CruiseControl distribution already a while ago. In other words, no need to download the stuff from the attached URLs--just use a recent enough version of CruiseControl and you're all set.

Well, since Mike hinted that it would be easy, I couldn't resist spending an hour to hack together a BloggerWeblogPublisher.java which posts the build results to a specified weblog using the Blogger API.

Just throw the publisher class to your CruiseControl directory, download xmlrpc-1.2-b1.jar into the lib directory, rebuild cruisecontrol.jar, and add these to your CruiseControl config.xml:

<cruisecontrol>
    <project name="foo">
        <plugin name="weblog" classname="net.sourceforge.cruisecontrol.publishers.BloggerWeblogPublisher"/>
        ...
        <publishers>
            <weblog blogurl="http://localhost:8080/pebble/xmlrpc"
                    blogid="blog"
                    username="lasse"
                    password="password"
                    category="CruiseControl"
                    reportsuccess="always"
                    subjectprefix="[CruiseControl]"
                    buildresultsurl="http://buildserver:8080/cruisecontrol/buildresults"                                                          logdir="/cruisecontrol/logs/foo"
                    xsldir="/cruisecontrol/reporting/jsp/xsl"
                    css="/cruisecontrol/reporting/jsp/css/cruisecontrol.css"/>

        </publishers>
    </project>
</cruisecontrol>

It's far from finished, but it seems to be "usable" already if you're itching to see your build results in your RSS aggregator. I'll submit it to the CruiseControl committers when it's a bit more polished...

The code is based on CruiseControl's EmailPublisher and HTMLEmailPublisher.
