Plugin Information

View IRC on the plugin site for more information.

This plugin enables Jenkins to send build notífications via IRC and lets you interact with Jenkins via an IRC bot. Note that you also need to install the instant-messaging plugin .

Installation Requirements

This plugin needs the instant-messaging plugin. Please ensure that the latest version of this plug-in is also installed.


See the  instant-messaging plugin for a description of protocol-independent features.

IRC-specific features

  • support password-protected chatrooms
  • support NickServ authentication
  • the rate at which messages are send is throttled to one every 500ms to avoid being subject of flood control on the IRC server.
    This rate can be configured with the system property hudson.plugins.ircbot.messageRate

Known Issues

Please look into the issue tracker for any open issues for this plugin.

Debugging Problems

If you experience any problems using the plugin please increase the log level of the logger hudson.plugins.ircbot to FINEST (see Logging), try to reproduce the problem and attach the collected logs to the JIRA issue.

  • feature: userstat command for bot (JENKINS-6147 )

  • This is the first version which is build upon the instant-messaging plugin. Make sure that instant-messaging 1.3 is installed.
  • This version needs Hudson 1.319 or newer
  • Though much care has been taken to migrate settings from previous versions, because of the amount of the changes it cannot be guaranteed that all old settings are migrated correctly!
  • This version supports all options that the Jabber plugin supports. See there for more info.
  • Command responses are no longer send as private messages to the user. Instead they are send to the channel. If you want private messages then send the command as a private message to the bot.


When you install this plugin, your Hudson configuration page gets additional "IRC Notification" option as illustrated below:

In addition, each project should add a "Post-build Actions"> "IRC Notification" configuration as illustrated below:

For the project configuration, leave the Channels blank to default to the channels defined in the master IRC configration.

    Any possible support for per-channel passwords?

      Should be possible - the biggest problem is how to make the UI for this. Please, create a new issue tracker item for it.

  2. I've begun to write a parser API for 2.X style IRC messages of this plugin. The API can be used to further process the messages, it just extracts the data.

    The source code can always be found here:

    The first version was created in context of an Open Source Love Day (OSLD):

  3. I think in the latest upgrade, the "Hudson username" and "Hudson password" fields were added (I don't remember them before...).  So, when I upgraded, it added two fields to the plugin xml to store this data, but, I never had the chance to set data for that.  So, Hudson would just never start up -- its startup process would freeze after joining the IRC room.  I eventually started poking around and saw the empty fields and filled them in with some user data, which, fixed my problem.  Anyway, someone else is probably having the same problem.  The xml file I edited was hudson.plugins.ircbot.IrcPublisher.xml .  I have a locked down Hudson, but, haven't had problems with the IRC bot in the past.

      Please use the issue tracker to report bugs! I don't monitor the comments.

  4. A feature request ! (wink)

    • Support of SSL connections to IRC Servers would be nice
    • Channelkeys should be supported.
