问题
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?

The snippet above (one of the reported problems) is part of the file from my project here: https://github.com/rcsenkbeil/scala-debugger/blob/master/scala-debugger-api/src/main/scala/org/senkbeil/debugger/Debugger.scala#L22

回答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
)
回答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
