scala what does this mean? "{ /* compiled code */ }"

Question

I came across this thing multiple times: { /* compiled code */ } but I can't find what it does in scala.

example:

object autoImport extends scala.AnyRef {
    ...
    val destination : sbt.SettingKey[java.io.File] = { /* compiled code */ }
    ...

}

It doesn't do anything. It's your IDE telling you that it can't find the source code for the given method and thus can't show it to you.

That's assuming you're looking at a class file in your IDE. If you're looking at actual Scala code, it's just an empty method with a severely misleading comment.
