Okay, 1st order of business, for anyone wondering how to "re-run with -feature" if that warning is thrown in the "reload" / "build project" compilation part, add a project/build.sbt file with content scalacOptions in ThisBuild ++= Seq("-feature") or whichever compiler flag you need. Having those options in build.sbt does not work.

Issue was with the code in Dependencies.scala. It was all this kind:

[warn] /home/simon/gitShared/opal_hiwi/project/Dependencies.scala:63: reflective access of structural type member value scalatest should be enabled
[warn] by making the implicit value scala.language.reflectiveCalls visible.
[warn]         val scalatest = "org.scalatest" %% "scalatest" % version.scalatest % "test,it"
[warn]                                                                  ^

I replaced the anonymous lazy vals with objects, everything solved. PR: https://bitbucket.org/delors/opal/pull-requests/448
