Have you tried setting <timeOut>? http://mojo.codehaus.org/gwt-maven-plugin/compile-mojo.html#timeOut
Also, one issue with the gwt-maven-plugin is that it always pass the -gen to the GWT Compiler (the <gen> in the POM), which can make extensive use of disk I/O (particularly when using UiBinder, RPC/RequestFactory, the Editor framework, ClientBundle, I18N, GIN, etc.), so you'll want that directory to be on a fast disk. There's no way of disabling this (yet! patches welcome) -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
