sbt-scala-native 0.3.3 and sbt 1.0

[turbolent]

I'm trying to get my code working with Scala Native and followed sbt-crossproject's README:
I rewrote my build.sbt file and added the sbt-crossproject and sbt-scala-native plugins to project/plugins.sbt:

addSbtPlugin("org.scala-native" % "sbt-crossproject" % "0.2.2")
addSbtPlugin("org.scala-native" % "sbt-scala-native" % "0.3.3")

I also set sbt.version=1.0.1 in project/build.properties.

Running sbt I get:

It looks like sbt-crossproject is published for Scala 2.12 and sbt 1.0,
but sbt-scala-native is not.

That's right. See scala-native/scala-native#915 which tracks sbt 1.x support for sbt-scala-native. sbt-crossproject already supports it.
