This requires almost everything we do now. Let's take source generation for example: you would still need to use configurators in order to generate sources and make the workspace aware of those sources. Otherwise a user imports a project and sources they need are not available. You either need to run Maven, an individual mojo or a configurator. Additionally it would just be even more confusing having two primary modes of operation and the surface area to support becomes problematic again. Users will complain that things don't work and I don't believe this is viable. I'm only interested in making it work properly which I consider full integration. I certainly wouldn't expend any effort here trying to make b) work. If you want static, non-realtime integration with Maven then the maven-eclipse-plugin is what you want. > /max > >> >>> Thank you very much, >>> Sahoo >>> >>> On Tue, Aug 9, 2011 at 10:45 PM, Max Rydahl Andersen >>> <[email protected]> wrote: >>> >>>> 1.
