I'm using sbt-web, and I'd like to only uglify js files for production (saves compile time while developing). However, when I run:
sbt prod:run
I get the same result as
sbt run
That is, prod:run doesn't seem to pickup the pipelineStages in prod scoped setting, below.
I'm certain that I am mis-understanding how this all works, and am hoping for some clarity and correct usage. I've read http://www.scala-sbt.org/0.13/tutorial/Scopes.html and every similar post on SO but the lightbulb hasn't turned on yet. I'm OK if there is a better way to do it, but because I'm in learning mode, I'd still like to know the reasons behind why this doesn't work.
Here is the full ./build.sbt file:
organization := "com.test123.spray"

scalaVersion := "2.11.6"
scalacOptions := Seq("-unchecked", "-deprecation", "-encoding", "utf8")

// client side dependencies

)
}
// sbt-web pipeline for combining, minifying, etc... client-side files
// see plugins.sbt for sbt dependencies that provide this capability.

)

// run uglify in prod only
pipelineStages in prod := Seq(concat, uglify, gzip)
