This looks some kind of consequence of the 2.12.13 upgrade? Note that @nowarn appears nowhere in this repo.

This was caught by the Scala community build.

offhand I'm guessing what's needed here is a 2.12.x backport of scala/scala#9491 (cc @lrytz)

[eed3si9n]

Yup. pure expression fix. I think we're getting closer tho since there's a way to suppress that no-warn-nowarn - sbt/sbt#6363

[SethTisue]

yay, fixed in 1.5.0-RC2.

closing — once 1.5.0 final is out, Scala Steward will submit an upgrade, I believe
