gwt-dev contains all sort of classes (from third parties, bundled into a fat-jar) that are quite likely to conflict with non-GWT dependencies. This is why you should setup different classpaths for GWT- and non-GWT-related (server-side) tasks; and with Maven you have no other choice than using distinct modules. > 2) It seems taking out gwt-dev causes SDM to not work, but other things > continue working.
