Scala does not work with Java 9 out of the box just yet - there is a way, but you have to be sure that various components in your mix have minimal versions required for compatibility.

See this compatibility matrix (notice Java, Scala and SBT versions)

The easiest fix is to run your Spark project in Eclipse using Java 8.
