Play Framework 2: Read the application version defined in Build.scala

Question

I use the Play Framework 2.0 (2.0.3). I have a Java project and want to read the application version (appVersion) defined in Build.scala.

What I already

Answer 1

I use the SBT BuildInfo plugin for this purpose:

import sbtbuildinfo.Plugin._

val main = PlayProject(appName, appVersion, appDependencies, mainLang = SCALA, settings = Defaults.defaultSettings ++ buildInfoSettings).settings(

  buildInfoKeys := Seq[Scoped](name, appVersion, scalaVersion, sbtVersion),
  buildInfoPackage := "org.foo.bar",

  ...

)

This generates an org.foo.bar.BuildInfo object which you can then call from the source code:

org.foo.bar.BuildInfo.version

You can also define custom keys in the build and add them to the buildInfoKeys, which is quite useful if your build gets more complex.
