Ccnet-hipchat-plugin is a project mainly written in ..., it's free.
Plugin for publishing build results to HipChat from CruiseControl.NET
A basic HipChat publisher for CruiseControl.NET.
Thanks to alexscordellis and his ccnet.campfire.plugin project which I used to figure out how to create a CruiseControl.NET publisher.
Once compiled, copy ccnet.hipchat.plugin.dll to C:Program Files (x86)CruiseControl.NETserver, or to where CruiseControl.NET is installed if not the default path.
Add the following to your ccnet.config publishers block:
<hipchat
https="true or false"
room-id="integer room id or string room name"
from="who the message is from, usually Robot Llama"
auth-token="your auth token"
/>
