Such a suggestion should be made to GWT development team ! As the GWT compilation process is complex (read modules XML, find client code and referenced objets...), there is no simple way to know some modified java source file requires a GWT recompilation...
The javac compiler is also executed on every build but is fine enough not to recompile up-to-date classes. The issue I was talking about is that the initial GWT Mojo did not avoid the GWTCompiler to System.exit() during the build. Do you speak from http://mojo.codehaus.org/gwt-maven-plugin/ ? I didn't notice this classpath error, could you report an issue with a test project ?
