scala plugin compile java source file with non-english comments report error on Mac

My project use sbt and play framework for Java.

I have some Chinese comments in my source file.My file encoding is UTF-8.

I set the encoding to UTF-8 in every place that I can find in IDEA.

When I build the project with make button in IDEA on my mbp, IDEA complains about ascii error.

But I can build the project in terminal with "sbt compile" command.

I also tried in Ubuntu, everything is fine.

After a while, I added this javac option in my build.sbt,  IDEA works fine on my mbp.

 
javacOptions ++= Seq("-encoding", "UTF-8")


I doubt is the problem about Scala Plugin in IDEA?
