[m2e-users] Classpath issue running JUnit/Application - Javassist Method

[Dave Hicks <dhdev@xxxxxxxxxxx>]

I've got a Maven based project that I work on using Eclipse and 
M2Eclipse.  I've encountered a problem with the classpath that only 
comes up when I attempt to run JUnit test cases and Application classes 
from within Eclipse.  I get a NoClassDefFound error on the Javassist 
"MethodFilter" class when trying to load the Spring application 
context.  All of these work without problem when I run the same tests 
and/or applications directly in Maven from the command line.  I have 
updated dependencies and project configuration on my project, but those 
did not have any effect.  I've also tried swapping between the built-in 
Maven instance (3.0 SNAPSHOT) included with M2Eclipse and my installed 
version (2.2.1).  That, too, had no effect.

I don't know for sure that this is an M2Eclipse issue.  It's just my 
first point of attack, having failed all other avenues that I could 
think of.  In looking at the .classpath file for my project, I see that 
the classpath refers to "MAVEN2_CLASSPATH_CONTAINER".  Is there some way 
that I can inspect that container to see what's really in it?  I'm just 
unsure how to debug this problem from here.

Thanks,
Dave
