Hi,

Sorry to disturb, and also sorry for using the bug tracker for ask for support -
I wasn't too sure where else to ask...

I'm having troubles installing the rake plugin for Hudson - I had it working
before, but following either a recent update in Hudson or the plugin, i've lost
the rake plugin.

I'm running Hudson on a Debian linux server, with Sun Java 1.5.0_17.

Looking through the logs, I get the following error messages on startup:

Sep 28, 2009 8:48:39 PM hudson.PluginManager <init>

Any ideas what could be wrong and what I can do to resolve this?

Thanks in advance for any help,

Darren
