如何参考外部本地sbt项目设置多模块构建? [英] How to set up multi-module build with reference to external local sbt project?

问题描述

我刚开始使用Scala和Play，并且尝试使用sbt 0.13.5设置多版本 我的项目结构如下:

I just started with Scala and Play and I'm trying to set up a multi build with sbt 0.13.5 My project structure is the following:

/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

该示例项目取决于AnormCypher项目.我尝试在这篇SO帖子.我的示例中的build.sbt看起来像这样:

The sample project depends on the AnormCypher project. I tried to set up the dependency following this SO post. My build.sbt in sample looks like this:

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)

当我进入控制台并键入

activator

sbt能够加载项目.但是，当我尝试编译源代码并尝试使用org.anormcypher包中的类时，无法解决它们:

sbt is able to load the project. But when I try to compile the sources and try to use classes from the org.anormcypher package, they can't be resolved:

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

运行clean compile也没有结果.

推荐答案

更改

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

到

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

然后删除

val main = root.dependsOn(core)

reload，该项目应该可以正常运行.

reload and the project should work fine.
