Subject cargo maven2 plugin causing exceptions during build because of commons-logging
Date Thu, 28 Aug 2008 09:18:57 GMT

Hey,

I've been attempting to load a test environment in a Jetty container for
JSFUnit through the cargo-maven2-plugin.  
Sadly every time the deployment to Jetty is attempted there is a huge list
of exceptions caused by Commons-logging.
When using no logger at all stderr is used for output, causing the following
exceptionstack, which is roughly the same if I use Log4j:

After some web searching I found an alternative for log4j or stderr, namely
slf4j.  However using this one still causes a similar exception stack:

I'm at a loss on how to get this issue fixed.  If anyone knows what to do,
by all means let me know ;-)
