For Play 2, you can create new tasks using SBT, by following the documentation here:

http://www.scala-sbt.org/release/docs/Detailed-Topics/Tasks

In the context of a Play 2 generated Build.scala, it might look like this:

import sbt._
import Keys._
import play.Project._

object ApplicationBuild extends Build { 

  val appName         = "foo"
  val appVersion      = "1.0-SNAPSHOT"

  val appDependencies = Seq(
    // Add your project dependencies here,
    jdbc,
    anorm
  )

  val hello = TaskKey[Unit]("hello", "Prints 'Hello World'")

  val helloTask = hello := {
    println("Hello World")
  }

  lazy val main = play.Project(appName, appVersion, appDependencies).settings(
    helloTask
  )
}
