You may also need to switch the Eclipse builder used from refined to sbt, see: http://scala-ide-portfolio.assembla.com/spaces/scala-ide/wiki/SBT-based_build_manager

However, there is a known bug with that which may or may not occur, see: http://scala-ide-portfolio.assembla.com/spaces/scala-ide/tickets/1000617-sbt-build-manager-and-certain-compiler-options-don-t-mix (allegedly fixed in latest overnight build).
