Scaladoc (2.11.6) fails on throws tag with "unable to find any member to link"

Question

When attempting to publish the jars for my project via sbt "++2.11.6 publishLocal" or sbt +publishLocal, I encounter Scaladoc issues when publishing for Scala 2.11.6. It appears that I have invalid links caused by the @throws tag. I am not sure why I have invalid links nor why the error only occurs for Scala 2.11.6 while not for Scala 2.10.5 during my cross-publishing. I can't find any indication that the @throws tag is not supported on Scala 2.11; so, I'm assuming it is an issue with my Scaladoc, but I don't know what I am missing at this point. Can anyone give me some insight into this issue?

Answer 1

Based on discussion here, I have decided to suppress the errors for now by adding the Scaladoc option -no-link-warnings.

scalacOptions in (Compile, doc) ++= Seq(
  "-no-link-warnings" // Suppresses problems with Scaladoc @throws links
)

Answer 2

Note that if you don't need scaladoc-s at all, you can make them empty:

sources in (Compile,doc) := Seq.empty

And not publish at all:

publishArtifact in packageDoc := false
