Question

当存在这一行时，Sbt会产生错误：

fork in run := true

周围的build.scala内容

  lazy val scalafxDemos = Project(
    id = "scalafx-demos",
    base = file("scalafx-demos"),
    settings = scalafxSettings ++ Seq(
      libraryDependencies ++= Seq(
        scalatest % "test",
        junit % "test"),
      unmanagedListing,
      description := "The ScalaFX demonstrations",
      fork in run := true,
      fork in Test := true,
      parallelExecution in Test := false,
      // print junit-style XML for CI
      testOptions in Test <+= (target in Test) map {
        t => Tests.Argument(TestFrameworks.ScalaTest, "-u", "%s" format (t / "junitxmldir"))
      },

产生错误：

[error] /Users/hanxue/Github/scalafx/project/build.scala:113: overloaded method value in with alternatives:
[error]   (scope: sbt.Scope)sbt.SettingKey[Boolean] <and>
[error]   (c: sbt.ConfigKey)sbt.SettingKey[Boolean] <and>
[error]   (t: sbt.Scoped)sbt.SettingKey[Boolean] <and>
[error]   (p: sbt.Reference)sbt.SettingKey[Boolean]

[error]       fork in run := true,
[error]            ^
[error] one error found
[error] (compile:compile) Compilation failed

我可以通过将行更改为fork := true来避免错误，但这确实满足仅在run和Test中分叉的意图。如何解决这个问题而不强迫其他所有东西分叉？

Answer 1

这可能意味着run来自其他地方。您可以尝试使用明确的Keys.run来查看是否属于这种情况。

启用分叉时sbt错误
