Getting things up and running with neither the magical Google Plug-in for Eclipse nor Eclipse itself is certainly tedious. The positive side of all this, is that one gets to know the details of what the system does. After finalising my Ant build script for GWT I struggled a lot with the App Engine part, until I noticed Google generously provided an ant_macros.xml file with the App Engine SDK! Having inported the definitions from that file, and copied some commands from some example project, I can now do quite a lot with the build file, including copying files, compiling them, packaging, running in hosted mode or through a local App Engine server, cleaning up directories, and my favourite: datanucleus enhance, just because it sounds so high-tech-sci-fi-y.
Tere are probably some libraries and procedures we don't really use in our project, but at this point I dare not modify things that work!
