如何参照外部本地sbt项目建立多模块构建？

Question

我刚刚开始使用Scala和Play，我正在尝试用SBT0.13.5设置一个多构建，我的项目结构如下：

/AnormCypher
   -> /src
      ->/main
        ->/scala
          ->org.anormcypher[package]
              ->[Some classes]
   -> [other dirs/files]
   -> build.sbt
/sample
   -> /src
      ->/main
        ->/scala
          ->/controllers[package]
              ->Application.scala
              ->[Some classes]
   -> [other dirs/files]
   -> build.sbt

示例项目依赖于AnormCypher项目。我试图在this SO post之后设置依赖项。示例中的build.sbt如下所示：

name := """sample"""

version := "1.0-SNAPSHOT"

lazy val root = (project in file(".")).enablePlugins(PlayScala)

scalaVersion := "2.11.1"

libraryDependencies ++= Seq(
  jdbc,
  anorm,
  cache,
  ws
)

lazy val core = ProjectRef(file("../AnormCypher"), "anormcypher")

val main = root.dependsOn(core)

当我进入我的控制台并键入

activator

sbt能够加载项目。但是，当我试图编译源代码并尝试使用org.anormcypher包中的类时，它们无法被解析：

object anormcypher is not a member of package org
[error] import org.anormcypher._
[error]            ^

运行clean compile也没有带来任何结果。

变化

lazy val root = (project in file(".")).enablePlugins(PlayScala)

至

lazy val root = (project in file(".")).enablePlugins(PlayScala).dependsOn(core)

移除

val main = root.dependsOn(core)

reload和项目应该能正常工作。
