interesting.... so could be bad packaging or a bug in GWT's handling
of stuff in dev mode.

A general question to the list: Should we put these in subversion for
now?... of course 'for now' may mean 'forever', since we will most
likely forget why we put it in there ")

The error I was getting before this one was because .classpath set a var to look for ehcache 1.6.1 in the repo but Sakai (trunk, and 2.8+) now use ehcache-core 1.7.2.  I changed .classpath to look for ehcache-core 1.7.2 instead, refreshed the workspace, and now am seeing those loggerfactory errors.  I believe this change in ehcache's artifactid/version was relatively recent, as in less than a year.

Sakai grabs 1.4.2 (both 2.8 and trunk) so this isn't something that could have been "resolved" by building Sakai trunk.

I figured, maybe I need to do the same thing with gb2 trunk, however the first jar that is missing is an older version than is already in my local maven repository (all previous problem jars were looking for newer versions).

So before you run GB2 in Eclipses DEV mode for the first time, you have to build Sakai (trunk) first, so that the build populates the maven repository with all the necessary artifacts.

For example, when I try to run the configuration eclipse errors saying that archive-api-1.3-SNAPSHOT.jar is missing when that is expected because that jar isn't in my m2repo since it is nowhere in the gb2 poms - at least, for the gb2 code we have.  This goes for other dependencies as well.
