It's actually just a slight improvement over the already existing maven_script.sh<http://code.google.com/p/google-web-toolkit/source/browse/trunk/tools/scripts/maven_script.sh> (using pre-written POMs rather than generating them)
That's actually not enough though, because GWT jars are created with a JarIndex, and a JarIndex contains the name of the JAR, so renaming it without regenerating or stripping the JarIndex (META-INF/INDEX.LIST) generates spurious exceptions in DevMode (caught internally, but very annoying if you "suspend executions on unhandled exceptions" when launching DevMode with a debugger attached: the CompilingClassLoader looks up classes in a gwt-user.jar instead of the gwt-user-2.4-SNAPSHOT.jar). Removing the JarIndex, or regenerating it, is easy, but still. -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
