libraryDependencies on sbt Build.scala Full Configuration wi

我有一个项目foo有两个孩子foo-core和foo-cli,foo-cli依赖于foo-core
(我来自 Java / Maven并尝试使用2个子模块架构转置父模块).
在 https://github.com/harrah/xsbt/wiki/Full-Configuration之后,我用这种方式编写了我的项目/ Build.scala：

import sbt._
import Keys._

object MyBuild extends Build {
      //Dependencies
      val slf4s = "com.weiglewilczek.slf4s" %% "slf4s" % "1.0.6"
      val slf4j = "org.slf4j" %% "slf4j-simple" % "1.5.6"
      val grizzled = "org.clapper" %% "grizzled-slf4j" % "0.5"
      val junit = "junit" % "junit" % "4.8" % "test"
      //End dependencies

  lazy val root : Project = Project("root",file(".")) aggregate(cli) settings(
    mainClass:= Some("Main")
  )

  lazy val core : Project = Project("core",file("core"),delegates = root :: Nil) settings(
    name := "foo-core",libraryDependencies ++= Seq(grizzled)

    )

  lazy val cli: Project = Project("cli",file("cli")) dependsOn(core) settings(
    name := "foo-cli",libraryDependencies ++= Seq(grizzled)
    )
}

这个配置不起作用：当我运行sbt reload; sbt update(如http://software.clapper.org/grizzled-slf4j/所示)时,不会下载grizzled库,因此当我编译时,“import grizzli._”在我的核心和cli项目中失败.

因为我是scala / sbt的新手,所以我想我做的很糟糕,但无法理解为什么因为我对所有sbt 0.7 / sbt0.10冲突的配置感到困惑
(如Subproject dependencies in SBT).

任何的想法？提示可以帮助我吗？

提前致谢
