TASTy signature has wrong version error

Ideally, I don’t think this should really ever surface to the user. For example, a minified version of a script I have is currently causing this:

// using scala 3
import $dep.`com.lihaoyi::requests:0.6.9`

object LatestVersion extends App {

  val metadataLoc = ""
  val creds = ""

  val existingResponse = requests.get(
    metadataLoc,
    headers = Map(
      "Authorization" -> s"Basic: $creds"
    )
  )

}

And when I try to scala-cli run <file> you see the following:

❯ scala-cli run Request.scala

I’d wager that a user won’t have any clue what this error means. To be honest, I don’t even understand how there is a mismatch here and I’m also unsure where 3.1.0-bin-nonbootstrapped is actually coming from.

Thank you for reporting. Btw I found the example can be even shorter:

// using scala "3.1.0"

object LatestVersion extends App {
  throw new RuntimeException("")
}

The above exception was thrown from pretty-stacktraces which was removed in ScalaCLI 0.1.5. So, this exception shouldn’t occur again.
