在sbt的build.sbt文件中添加模块依赖性信息

Question

我在IntelliJ中有一个多模块项目，如此屏幕截图所示，contexProcessor模块依赖于contextSummary模块。

一旦我在Project Structure中设置了依赖项，IntelliJ就会处理所有事情。

但是，当我在sbt test中使用以下设置运行build.sbt时，我收到错误，抱怨它无法在contextSummary模块中找到包。

name := "contextProcessor"

version := "1.0"

scalaVersion := "2.11.7"

libraryDependencies += "org.scalatest" % "scalatest_2.11" % "2.2.2" % "test"

如何教导找到丢失的模块？

Answer 1

我可以使用主根目录中的build.sbt文件。

lazy val root = (project in file(".")).aggregate(contextSummary, contextProcessor)
lazy val contextSummary = project
lazy val contextProcessor = project.dependsOn(contextSummary)

参考：http://www.scala-sbt.org/0.13.5/docs/Getting-Started/Multi-Project.html

仅测试一个项目，我可以在project中使用sbt命令。

> sbt
[info] Set current project to root (in build file:/Users/smcho/Desktop/code/ContextSharingSimulation/)
> project contextProcessor
[info] Set current project to contextProcessor (in build file:/Users/smcho/Desktop/code/ContextSharingSimulation/)
> test

对于批处理模式，如How to pass command line args to program in SBT 0.13.1?

sbt "project contextProcessor" test

我认为一个简单的build.sbt可能还不够。

你需要创建一个更复杂的项目/ Build.scala ：

import sbt._
import sbt.Keys._

object Build extends Build {
  lazy val root = Project(
    id = "root",
    base = file("."),
    aggregate = Seq(module1, module2)
  )

  lazy val module1 = Project(
    id = "module1",
    base = file("module1-folder"),
    settings = Seq(
      name := "Module 1",
      version := "1.0",
      scalaVersion := "2.11.7",
      libraryDependencies += "org.scalatest" % "scalatest_2.11" % "2.2.2" % "test"

  lazy val module2 = Project(
    id = "module2",
    base = file("module2-folder"),
    dependencies = Seq(module1),
    settings = Seq(
      name := "Module 2",
      version := "1.0",
      scalaVersion := "2.11.7",
      libraryDependencies += "org.scalatest" % "scalatest_2.11" % "2.2.2" % "test"
}
