如何在SBT .scala项目配置中从多个非托管目录添加jar

unmanagedBase := file( "custom-libs" ).getAbsoluteFile

但由于我有两个带有非托管jar的目录,我需要能够将它们全部添加.我找到了一些信息in here,但对我的完整.scala文件构建似乎没有用.

我创建了一个简单的项目,显示问题in here.以下是我的Build.scala文件.

UPDATE

我从sbt-users list获得了一些帮助,并且能够正确定义非托管jar,但代码仍然无法编译(但是sbt show unmanaged-jars正确显示文件).

import sbt._
import com.github.siasia._
import PluginKeys._
import Keys._

object Build extends sbt.Build {

  import Dependencies._

  val unmanagedListing = unmanagedJars :=  {
    Dependencies.listUnmanaged( file(".").getAbsoluteFile )
  }

  lazy val myProject = Project("spray-template",file("."))
    .settings(WebPlugin.webSettings: _*)
    .settings(port in config("container")  := 8080)
    .settings(
      organization  := "com.example",version       := "0.9.0-RC1",scalaVersion  := "2.9.1",scalacOptions := Seq("-deprecation","-encoding","utf8"),resolvers     ++= Dependencies.resolutionRepos,libraryDependencies ++= Seq(
        Compile.akkaActor,Compile.sprayServer,Test.specs2,Container.jettyWebApp,Container.akkaSlf4j,Container.slf4j,Container.logback
      ),unmanagedListing
    )

}

  val resolutionRepos = Seq(
    ScalaToolsSnapshots,"Typesafe repo" at "http://repo.typesafe.com/typesafe/releases/","spray repo" at "http://repo.spray.cc/"
  )

  def listUnmanaged( base : RichFile ) : Keys.Classpath = {
    val baseDirectories = (base / "custom-libs") +++ ( base / "custom-libs2" )
    (baseDirectories ** "*.jar").classpath
  }
