Buggy in scala 3.3, but fixed in 3.4.1: scala/scala3#18804
And a possible workaround: typelevel/sbt-tpolecat#134 (comment)

Also intellij can't handle the scalacOptions being different between test and main when using the built-in compiler, if you're running into that remove the Test / part and it'll use the same flags in both main and test. A little less clean but it gets the job done

I had to add more. Like this:

    "-Wconf:msg=unused value of type org.scalatest.Assertion:s",
    "-Wconf:msg=unused value of type org.specs2.specification.core.Fragment:s",
    "-Wconf:msg=unused value of type org.specs2.matcher.MatchResult:s",
    "-Wconf:msg=unused value of type org.scalamock:s"
