ScalaTest需要多项目sbt的设置

Question

我既不能运行测试，因为它们中的任何一个都被检测到，当编译器抱怨时，这是为了解释当我在核心项目中交互地运行sbt时，我不能从/ core /src/main in /core/src/test导入类。

下面是我使用的基本配置。

文件夹组织

|
| build.sbt
|
|-------------- core | src ------------| main | scala | files...
|                    | build.sbt       | test | scala | files...
|
|-------------- proj1 | src ----------- | main | scala | files...
|                     | build.sbt       | test | scala | files...

这里有一些build.sbt的和平

lazy val deps = Seq(
    "org.scalactic" %% "scalactic" % "3.1.2",
    "org.scalatest" %% "scalatest" % "3.1.2" % "test"
)

lazy val coreDeps = libraryDependencies ++= deps


lazy val core = (project in file("core"))
   .settings(coreDeps)

lazy val proj1 = (project in file("proj1"))
  .settings(coreDeps)
  .dependsOn(core)

Answer 1

问题来自于build.sbt文件，这些文件在core和proj1下，一旦我删除了它们，一切都按预期工作。

Answer 2

您只需按照注释中的内容执行:使用settings方法应用设置：

lazy val core = (project in file("core"))
  .settings(
    libraryDependencies ++= Seq(
      "org.scalactic" %% "scalactic" % "3.1.2",
      "org.scalatest" %% "scalatest" % "3.1.2" % "test"
    )
  )

lazy val proj1 = (project in file("proj1"))
  .settings(
    libraryDependencies ++= Seq(
      "org.scalactic" %% "scalactic" % "3.1.2",
      "org.scalatest" %% "scalatest" % "3.1.2" % "test"
    )
  )

或者，您可以将libraryDependencies键作用于ThisBuild。然后，它将在所有子项目中继承：

ThisBuild / libraryDependencies ++= Seq(
  "org.scalactic" %% "scalactic" % "3.1.2",
  "org.scalatest" %% "scalatest" % "3.1.2" % "test"
)

lazy val core = (project in file("core"))
lazy val proj1 = (project in file("proj1"))
