I was having the same problems using jetty's hot deploy with ~ prepare- webapp in sbt so I switched to using JavaRebel. It works much better and I haven't had any problems with reloading since. I don't think there's any info on the sbt site about jrebel, but it's real easy to get set up. Just install it and get a license (free for scala use) from them at: http://www.zeroturnaround.com/scala-license/
Then change your sbt script to: java -Xmx256M -noverify -javaagent:/path/to/javarebel-2.0.2/ javarebel.jar -jar `dirname $0`/sbt-launcher-0.5.1.jar "$@" I did run into a problem using an embedded H2 database, which may or may not occur with Derby, when using jetty-run/jetty-stop from the sbt prompt. What happens is jetty-stop does not shutdown the jvm, so H2 doesn't shut down. To get around this I use "sbt jetty" directly in the terminal, that way when you stop it, the jvm shuts down and the db with it. I then have a second terminal that I open an sbt prompt in and use ~ prepare-webapp. For me, this setup has worked much better.
