Failed javadoc downloads with sbteclipse when using with-source=true

Question

When I invoke sbt and type eclipse with-source=true, I get a bunch of failed javadoc downloads:

It looks like the javadoc jar files are simply missing from both the public Maven repository, and Sonatype's repository.

Why are so many javadoc files missing for these reasonably popular packages?

What repository is guaranteed to have a lot of these javadoc packages?

Answer 1

From within the play console, type "update-classifiers" to retrieve the sources and javadoc, or "eclipsify with-source=true" to include them in the generated eclipse project. (excluding the quotes)
