Scala's poor documentation stems from a much more fundamental problem - the absence of a Clojars/Rubygems/PyPI for Scala libraries. It's in the process of being fixed now, I believe, but why did it take so long? The Clojure community has a much lower profile in industry than Scala yet right from the beginning they really valued their community and produced an excellent repository for Clojure libraries and an easy-to-use build tool - Leiningen. The Scala community, by contrast, comes across to outsiders as just not that interested in community. Maybe it's the Java legacy.
