This warning has nothing to do with Tycho or Maven. Instead, it is
caused by the org.eclipse.xtext.ui.internal.Activator causing Log4J to
be initialized which in turn complains that you didn't set up your
logging configuration.
Now, a quick Internet search indicates yields [1], which indicates that
you could get rid of this message by explicitly requesting the
org.eclipse.xtext.logging fragment to be part of the surefire run. Have
a look at [2] for information on how to add extra
features/bundles/fragments to the runtime during test execution.
Hope this helps.
Andreas
