@unchecked annotations are not carried over to instrumented code

[RichardBradley]

(Low priority)

Code which has partial match functions which are annotated with @unchecked will raise a false compiler warning when instrumented with scoverage.

For example:

object PartialMatchObject {
  def partialMatchExample(s: Option[String]): Unit = {
    (s: @unchecked) match {
      case Some(str) => println(str)
    }
  }
}

The above code will give a "match may not be exhaustive" false compiler warning on sbt scoverage:compile (it will not give a compiler warning when compiled normally).

I reckon the annotation is not being copied by the plugin transformation phase. Now I have a way of debugging directly inside intellij should be easy to fix.

BTW I don't have your email address so:

Do you think that SBT is

1. A well thought out simple to easy build tool
2. A complete piece of shit

?

[RichardBradley]

It’s definitely not the first.
The second is a bit vague. It has serious problems that are probably insurmountable.
I've sent you an email with my thoughts.
