Question

I have an SBT scala application that runs fine using “sbt run”. However, this locks up the console, and I’d rather start it as a service/daemon so that I can use the console, and also so that I can add it to init.d to ensure that my application is started automatically on startup.

I can’t seem to find a way to do this. Running “sbt run &” seems to hang the app in the background.

Does anybody know how to do this?

We launch test/demo apps with SBT in init.d all the time:

#!/bin/sh
# test lift web app

case "$1" in
'start')
    cd /home/demouser/wa/HTML5DemoLift231/HTML5demo/
    sbt jetty run
    ;;
'stop')
    cd /home/demouser/wa/HTML5DemoLift231/HTML5demo/
    sbt jetty stop
    ;;
*)
    echo "Usage: $0 { start | stop }"
    ;;
esac
exit 0

This just works – we have had no problems with it. It may be different with a non-web app though.
