is this "mvn archetype:generate" up to date? I don't know if anybody guarantees it will work at all.. Anyway, the default way to at least try Lift and see it working is the following: https://github.com/lift/lift_25_sbt
It uses "Simple Build Tool" instead of maven, but maven should work, too. Also, you can easily read "build.sbt" to get all the dependencies. Plugins for creating eclipse/intellij project definitions are included. (See the README of the demo project.)
The target to create eclipse project is "eclipse" or "eclipse with-sources=true". The target to launch the app is "container:start".
