GWT Gadget for iGoogle No Compiler Output

Question

Hi, I'm trying to build a gadget with the GWT plugin for eclipse. Following the instructions Here: http://code.google.com/p/gwt-google-apis/wiki/GadgetsGettingStarted

it says I'll get several .cache.js files produced and a *.xml file. I don't see either of these, just the nocache.js file and a few images.

I've also tried importing the hellogadgets sample that comes with the gadget api, this has all the compiled output under war/hellogadgets, but if I remove these files and get eclipse to rebuild I get the same .nocache.js and some images.

Any ideas what the missing step is?

Thanks JG
