Whenever a job specify an IRC channel that is not defined in the global configuration, the IRC bot is not able to send to that channel.

Given a job like:

<publishers>
<hudson.plugins.ircbot.IrcPublisher>
<targets>
<hudson.plugins.im.GroupChatIMMessageTarget>
<name>#wikimedia-test</name>
<notificationOnly>false</notificationOnly>
</hudson.plugins.im.GroupChatIMMessageTarget>
</targets>
<strategy>ALL</strategy>
<notifyOnBuildStart>true</notifyOnBuildStart>
<notifySuspects>false</notifySuspects>
<notifyCulprits>false</notifyCulprits>
<notifyFixers>false</notifyFixers>
<notifyUpstreamCommitters>false</notifyUpstreamCommitters>
<buildToChatNotifier class="hudson.plugins.im.build_notify.DefaultBuildToChatNotifier"/>
<matrixMultiplier>ONLY_CONFIGURATIONS</matrixMultiplier>
<channels/>
</hudson.plugins.ircbot.IrcPublisher>
</publishers>

The resulting FINEST log for 'hudson.plugins.ircbot' gives out:

Mar 27, 2013 12:09:14 PM hudson.plugins.ircbot.v2.PircListener onServerResponse
WARNING: IRC server responded error 404 Message:
mw-jenkinsbot #wikimedia-test :Cannot send to channel
Mar 27, 2013 12:09:14 PM hudson.plugins.ircbot.v2.PircListener onServerResponse
WARNING: IRC server responded error 404 Message:
mw-jenkinsbot #wikimedia-test :Cannot send to channel

There are several ways to solve this issue. Either:

• in job configuration, only list the globally configured channels. Maybe using a list to pick from.
• dynamically register channels on job save and make the bot join. Could be made an optional feature.

Also, with the default login level, the plugin does not warn that it has not been able to send the notification. The console shows:

Started by user hashar
Building on master in workspace /var/lib/jenkins/jobs/Test - IRC notification/workspace
IRC notifier plugin: Sending notification to: #wikimedia-test
Finished: SUCCESS

Which is a bit misleading.
