Intellij SBT 项目：如何更改内容根目录？

Question

这是我项目中当前的内容根配置：

但是，我希望 "scala" 目录是实际测试内容的根目录，而不是名为 "test" 的目录。如果我修改它，我会收到 "Module is imported from Sbt. Any changes in its configuration will may be lost after re-importing." 的警告（事实上，它们是）。

不幸的是，我找不到在我的 Build.scala 文件（或任何其他文件）中声明此配置的位置。我能做些什么来一劳永逸地说服 IntelliJ "scala" 是正确的测试内容根？

这是我的 Build.scala 文件（如果重要的话，这是一个 Play 2.5.4 项目）：

import play.routes.compiler.StaticRoutesGenerator
import play.sbt.PlayScala
import play.sbt.routes.RoutesKeys._
import sbt.Keys._
import sbt._

object Build extends Build {
  val main = Project("Mp3Streamer", file(".")).enablePlugins(PlayScala).settings(
    scalaVersion := "2.11.8",
    version := "1.0-SNAPSHOT",
    addCompilerPlugin("org.scalamacros" % "paradise" % "2.1.0" cross CrossVersion.full),
    libraryDependencies ++= Seq(
      // a bunch of dependencies
    ),

    resolvers += Resolver.mavenLocal,
    javaOptions ++= Seq("-Xmx4000M", "-Xms2024M", "-XX:MaxPermSize=2000M"),
    routesGenerator := StaticRoutesGenerator
  )
}

通过将 scalaSource in Test := baseDirectory.value / "test" "/scala", 添加到我的 Build.scala 文件，我已经能够将 "scala" 文件夹设为测试源，但父 "test" 文件夹仍然也是测试来源：

据我所知，这是从 Play 继承的设置，因为如果我删除 .enablePlugins(PlayScala) 代码，"test" 文件夹将不再是测试源。按照https://www.playframework.com/documentation/2.5.x/Anatomy#Default-SBT-layout, I disabled the play layout, and then manually added the source and resource directories, which I copied from https://github.com/playframework/playframework/blob/master/framework/src/sbt-plugin/src/main/scala/play/sbt/PlayLayoutPlugin.scala#L9中的说明，只修改测试源，添加我自己的资源文件夹。我修改后的 Build.scala 文件现在是：

val main = Project("Mp3Streamer", file("."))
      .enablePlugins(PlayScala)
      .disablePlugins(PlayLayoutPlugin)
      .settings(
           target := baseDirectory.value / "target",

           sourceDirectory in Compile := baseDirectory.value / "app",
           // My change
           sourceDirectory in Test := baseDirectory.value / "test" / "scala",

           resourceDirectory in Compile := baseDirectory.value / "conf",

           scalaSource in Compile := baseDirectory.value / "app",
           // My change
           scalaSource in Test := baseDirectory.value / "test" / "scala",
           // I've added this resource
           resourceDirectory in Test := baseDirectory.value / "test" / "resources",

           javaSource in Compile := baseDirectory.value / "app",

           sourceDirectories in(Compile, TwirlKeys.compileTemplates) := Seq((sourceDirectory in Compile).value),
           sourceDirectories in(Test, TwirlKeys.compileTemplates) := Seq((sourceDirectory in Test).value),

           // sbt-web
           sourceDirectory in Assets := (sourceDirectory in Compile).value / "assets",
           sourceDirectory in TestAssets := (sourceDirectory in Test).value / "assets",


           resourceDirectory in Assets := baseDirectory.value / "public",

           // Native packager
           sourceDirectory in Universal := baseDirectory.value / "dist",

           // Everything else is the same as the original Build.scala file

老实说，这感觉太老套了，我可能最终会修改我的目录结构以匹配 Play 的默认设置...但重要的是原则！
