How to Add Environment Profile Config to SBT

Question

In Maven you can have Profiles, which can set up a build configuration for different environments. For example DEV, QA, UAT, PRODUCTION

In order to support continuous integration, there must be a way to tell SBT which environment to run against.

how to set up for different environments in SBT. For example DEV, QA, UAT, PRODUCTION?

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")))
}
