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

This was with both Java 1.5 and 1.6 on Debian Linux.
hpgen-1-14[team87]43: java -version
java version "1.6.0_14"
Java(TM) SE Runtime Environment (build 1.6.0_14-b08)
Java HotSpot(TM) 64-Bit Server VM (build 14.0-b16, mixed mode)
Sorry to be a pain, but it would be really great to be able to use this plugin.
Thanks again,
Darren
