-<!-- The following probably does not work. In that case
-     take a look at http://www.smartclient.com/builds/SmartGWT/
-     select a recent version and install it manually to fullfill
-     the smartgwt dependency:
-
-     mvn com.isomorphic:isc-maven-plugin:install -Dproduct=SMARTGWT \
-     -Dlicense=LGPL -DbuildNumber=4.1p -DbuildDate=2014-11-19
-
-     As patch builds for smartgwt do have regressions and are
-     regulararly removed from their repository we use a specific
-     version here that is known to work for us.
-
-     "Theoretically" any smartgwt version > 4.1 should do.
