It depends what you do with your pom.xml, i.e. how you use the dependencies. > I was uploading my gwt app on app engine, I got the error > saying gwt-user jar is too big, and I need to split it. > I decided to comment out gwt-user, and I didn't get any error or warning, > which made me wonder what dependencies I need to include in my build ? > See http://code.google.com/webtoolkit/doc/latest/DevGuideDeploying.html > and is there a library that need to be present in development mode, that > should be excluded in final build ? > DevMode and Compiler classes are in gwt-dev.jar, and all the code you use to build your app is in gwt-user.jar. Almost everything in gwt-user.jar is aimed at being compiled to JavaScript, the rest is present in gwt-servlet (making gwt-servlet a subset of gwt-user; well, there might be a few classes from gwt-dev too that are also copied to gwt-servlet, but that's an implementation detail). In brief, you need gwt-dev and gwt-user to build your client-side code, and you need gwt-servlet (and only gwt-servlet) on the server-side (and only if you use GWT-RPC and/or RequestFactory). This means that if your mix client-side and server-side code in your Maven module, you need to have gwt-user as <scope>provided</scope> (it's indeed provided by the gwt-maven-plugin) and gwt-servlet as <scope>runtime</scope> (gwt-dev is provided by the gwt-maven-plugin, so you don't need an explicit dependency, unless you have to write a generator or linker, but then beware of conflicts with some libraries; you'd better split your app into a client-side only and server-side modules) -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
