Play Framework 2.1: Use play.api.Configuration in Build.scala

Question

In the top answer to Play Framework 2: Read the application version defined in Build.scala it\'s suggested that the application version number be specified in conf/app

Answer 1

I works in 2.1-RC2 if you use typesafe's config library directly, without Play's Configuration wrapper. It's a Java API, so it is used slightly different than described in this answer.

In project/Build.scala import the library:

import com.typesafe.config._

and load the configuration from the file manually. Calling resolve() is needed to resolve substitutions.

val conf = ConfigFactory.parseFile(new File("conf/application.conf")).resolve()

val appName    = conf.getString("app.name")
val appVersion = conf.getString("app.version")
