sbt error when forking is enabled

Sbt produce an error when there is this line:

fork in run := true

in this build.scala file

The surrounding build.scala content

  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"))
      },

The error produced:

[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]  cannot be applied to (run.type)
[error]       fork in run := true,
[error]            ^
[error] one error found
[error] (compile:compile) Compilation failed

I can avoid the error by changing the line to fork := true, though that does satisfy the intent of forking only in run and Test. How can I fix this without forcing everything else to be forked?

That probably means run is coming from somewhere else. You might try an explicit Keys.run to see if this is the case.
