I'm new to maven so I just followed the Lift Getting Started guide, which uses "mvn jetty:run" to start jetty and ctrl-c to stop it.
I used sbt before for another project that uses a different framework and like it that it auto-compiles the changed files and restarts jetty (as far as I remember - it's been a while.) So far I haven't tried JRebel yet so I'm not sure if it offers more than what sbt does but I'm interested in finding out. When doing that project, I pretty much used a simple text editor to write scala code and I missed the features provided by eclipse or netbeans. So I'm hoping that there is a way to use sbt and eclipse or netbeans (I think the netbeans scala plug-in works better than the eclipse's plugin but I'm OK with usine eclipse since that's my default Java environment), and maybe add JRebel to the picture if it does something that sbt doesn't offer. I understand that the dev environment is a personal choice but I think it would be nice to have a recommended set up that makes use of neat tools like sbt and the free JRebel library. It would be helpful for people who are new to Lift or Scala in general. On Mon, Jan 18, 2010 at 10:58 PM, Naftoli Gugenheim <naftoli...@gmail.com> wrote: > How do you launch jetty?
