Command line options in SBT native packager

When you package a command-line application in SBT using the sbt-native-packager plugin, you get a wrapper script that has additional command line options that looks something like this:

  -h | -help         print this message
  -v | -verbose      this runner is chattier
  -d | -debug        set sbt log level to debug
  -no-version-check  Don't run the java version check.
  -mem <integer>     set memory options in MB (default: , which is -Xms1024m -Xmx1024m -XX:MaxPermSize=256m -XX:ReservedCodeCacheSize=128m)
  -jvm-debug <port>  Turn on JVM debugging, open at the given port.

  # java version (default: java from PATH, currently java version "1.7.0_21")
  -java-home <path>         alternate JAVA_HOME

  # jvm options and output control
  JAVA_OPTS          environment variable, if unset uses ""
  -Dkey=val          pass -Dkey=val directly to the java runtime
  -J-X               pass option -X directly to the java runtime
                     (-J is stripped)

  # special option
  --                 To stop parsing built-in commands from the rest of the command-line.
                     e.g.) enabling debug and sending -d as app argument
                     $ ./start-script -d -- -d

Is it possible to either selectively disable some of this options or remove them altogether from the packaged application?

Solution

First of all, there isn't any way to disable single command line options.

However, you can do a few other things:

As Shyam mentioned, you can override the start script
The second option would be to use the -- separator. Everything before that will be parsed by the script, and everything after will be appended as command line arguments to the application.

If you have a use case that may be of interest for general availability, you can open a feature request.
