I know it has already been touched on in the forums, but we really need a good way to integrate the SDK build process with Maven. This is really essential in larger enterprises where the build process is dictated down to the dev teams.
I know it's possible to install the SDK on a build server and execute it through a command line call, but a requirement like that isn't going to fly here. We need a standard way to run this without a dependency on installing additional software on the build server.
Even though I use Maven on a daily basis, I'm afraid I don't know much about it's inner workings or how one goes about creating a plugin. So I probably wouldn't be of much help myself, other than being able to offer help testing it.
This really needs to be addressed by Sencha. I can say from first-hand experience that upper management looks very dubiously at an "enterprise RIA platform" that doesn't support Maven. Especially when it's a commercial product.
It seems to me that the really hard part will be coming up with a JAR to run the actual ExtJS/Touch build. Right now it's Windows-specific, as far as I can tell. Where I'm at, the build servers are Ubuntu, so somehow the Sencha portion of the build needs to be platform-agnostic. So I'm really not sure there's much we can do from the outside...it seems like this is something Sencha would need to create?
