How to Add Environment Profile Config to SBT

You can do this by creating a custom configuration.

val ProfileDev = config("dev") extend(Runtime)
val ProfileQA  = config("qa") extend(Runtime)

val root = (project in file(".")).
  configs(ProfileDev, ProfileQA). // add config here!
  settings( 
    name := "helloworld",
    ....
  ).
  settings(inConfig(ProfileDev)(Classpaths.configSettings ++ Defaults.configTasks ++ Defaults.resourceConfigPaths ++ Seq(
    unmanagedResourceDirectories += {baseDirectory.value / "src" / configuration.value.name / "resources"}
  )): _*).
  settings(inConfig(ProfileQA)(Classpaths.configSettings ++ Defaults.configTasks ++ Defaults.resourceConfigPaths ++ Seq(
    unmanagedResourceDirectories += {baseDirectory.value / "src" / configuration.value.name / "resources"}
  )): _*)

You then place your config file in src/dev/resources and src/qa/resources, and it should be part of your classpath when you say dev:run or dev:package. Here’s a quick test:

object Main extends App {
  println(xml.XML.load(this.getClass.getResource("/config.xml")))
}
