如何在 sbt 的子模块中继承非托管依赖项？

Question

我有一个看起来像这样的项目，使用 sbt 0.13.2：

base
 - project
   - Build.scala
   - plugins.sbt
 - lib
   - unmanaged jar #1
   - unmanaged jar #2
 - core
    - src
      - .......
 - clp
    - src 
      - .......
 - server
    - src
      - ......

其中core 包含公共代码，clp 和server 是两个相关项目，它们都依赖于core。

我正在尝试在 Build.scala 中找到正确的 mojo，以便所有这三个模块都依赖于 base/lib。目前我在每个模块中使用符号链接lib 目录作弊，但我想在没有符号链接的情况下自动完成。

这是Build.scala 文件的示例 - 我应该如何修改它以使依赖项工作？

import sbt._
import Keys._

object RootBuild extends Build {
  lazy val buildSettings = Defaults.defaultSettings ++ Seq(
    scalaVersion := "2.11.1",
    unmanagedBase := baseDirectory.value / "lib"
  )

  lazy val standardSettings = buildSettings ++ Seq(
    libraryDependencies ++= Seq(
      "org.scalatest" % "scalatest_2.11" % "2.1.6" % "test",
      "org.testng" % "testng" % "6.8.8"
    )
  )

  lazy val Projects = Seq(root, core, clp)

  lazy val root = Project("root", file("."), settings=standardSettings) aggregate(core, clp)
  lazy val core = Project("core", file("core"), settings=standardSettings)
  lazy val clp = Project("clp", file("clp"), settings=standardSettings) dependsOn core
  lazy val server = Project("server", file("server"), settings=standardSettings) depensOn core
}

这是一个正确的build.sbt：

lazy val a, b = project settings(
  Defaults.defaultSettings ++ Seq(
    unmanagedBase := (unmanagedBase in ThisProject).value
  ): _*
)

想法是根据根项目中设置的值（隐式定义）为子模块设置unmanagedBase。

在您的特定情况下，如下所示：

import sbt._
import Keys._

object RootBuild extends Build {
  lazy val buildSettings = Defaults.defaultSettings ++ Seq(
    scalaVersion := "2.11.1"
  )

  lazy val standardSettings = buildSettings ++ Seq(
    libraryDependencies ++= Seq(
      "org.scalatest" % "scalatest_2.11" % "2.1.6" % "test",
      "org.testng" % "testng" % "6.8.8"
    )
  )

  lazy val submoduleSettings = standardSettings ++ Seq(
    unmanagedBase := (unmanagedBase in ThisProject).value    
  )

  lazy val root = project in file(".") settings(standardSettings: _*) aggregate(core, clp)
  lazy val core = project settings(submoduleSettings: _*)
  lazy val clp = project settings(submoduleSettings: _*) dependsOn core
  lazy val server = project settings(submoduleSettings: _*) dependsOn core
}
