IF you look in Scala's SBT build, we exposed the raw files used by

It's not the cleanest of builds, which I keep meaning to clean up, but
it's all in there. Hope that helps!

Hi all,
I want to define a task which basically calls some existing *ant* task from
scala compiler (scala.tools.ant.ScalaTool).
My build file in project/Build.scala looks like this:
import sbt._
import Keys._
import scala.tools.ant.ScalaTool
//import org.apache.tools.ant.taskdefs.MatchingTask
object SomeBuild extends Build {
val exSettings = Defaults.defaultSettings ++ Seq(
organization := "examples",
name := "ant-task-executor",
version := "0.1",
scalaVersion := "2.9.1",
scalacOptions in Compile ++= Seq("-unchecked", "-deprecation",
"-feature", "-Yoverride-objects"),
javacOptions += "-Xss2M",
resolvers ++= Seq("snapshots" at
"https://oss.sonatype.org/content/repositories/snapshots/")
//logLevel := Level.Debug
)
val generateScripts = TaskKey[Unit]("generate-scripts", "Generate
scripts")
val generateScriptsTask = generateScripts <<= (baseDirectory) map {(base)
=>
val task: ScalaTool = new ScalaTool()
}
lazy val root =
Project("testing",file (".")).settings((exSettings ++
List(generateScriptsTask)):_*)
}
and dependencies file in project/buildSettings.sbt is this:
libraryDependencies += "org.scala-lang" % "scala-compiler" % "2.9.2"
libraryDependencies += "org.apache.ant" % "ant" % "1.8.2"
Now, compiling the project is fine, but it fails when running the
'generate-scripts' task with:
sing /home/hubert/.sbt/0.12.1 as sbt dir, -sbt-dir to override.

which looks like it just doesn't add ant jar to the classpath but well that

I am probably getting it wrong but I would appreciate any hints.
