Unable to use doodle's GitHub master as a RootProject in sbt about doodle

[xanderdunn]

I tried cloning the doodle repository myself and then referencing it locally:

lazy val doodleProject = RootProject(file("./doodle"))

Same result.

I haven't seen this error before. My guess, from the line

Directory /local/dev/gridworld/js is not contained in build root

is it has something to do with the Scala.js plugin. If you don't already have it in your project you might try adding it. See https://github.com/underscoreio/doodle/blob/develop/project/plugins.sbt for the configuration that Doodle uses. You should only need

resolvers ++= Seq(
  Resolver.bintrayRepo("scala-js", "scala-js-releases")
)

addSbtPlugin("org.scala-js" % "sbt-scalajs" % "0.6.4")

If this doesn't help I would try asking on the sbt mailing list or Gitter channel https://gitter.im/sbt/sbt

From help on the sbt Gitter channel, apparently sbt-scalajs' cross building functionality is not compatible with sbt 0.13.8's added support for cross-Scala version sources and requires it to be re-set verbosely: https://github.com/InTheNow/export-hook/commit/22536a24f63eed647ce0ebd072758c752c88b1cc#commitcomment-12523097

Now I'm just trying to figure out how to apply this to my situation. Or, perhaps roll back sbt to 0.13.7.

It doesn't look like there's a clear workaround to this right now. It isn't actually solved by using a lower version of sbt:
