scala - How get application version in play framework and build.sbt

Question

I'm using play 2.2 with Scala, how can I get version from build.sbt?

name := "project_name"
version := "0.2-SNAPSHOT"

play.Project.playScalaSettings

or how can I pass there value from another object?

Answer 1

I've added this to my build.sbt:

import com.typesafe.config._

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

version := conf.getString("app.version")

and in my application.conf:

app.version="0.2-SNAPSHOT"
