Seeing this in my console after running play -> run
:
[warn] there were 1 feature warning(s); re-run with -feature for details
[warn] one warning found
Where is this enabled? Would like to see what the warning is, but running play -feature
or run -feature
doesn't seem to do the trick.
I'm running Play Framework 2.2.0-scala
-feature
is a compiler option - it must be passed to scalac.
To pass arguments to scalac
in play or in any sbt build for that mattern you use the scalacOptions
setting.
So add this in your build.sbt
:
scalacOptions += "-feature"
