Source downloads fail for grizzled-slf4j, junit, scalatest, logback

Hello!

The .pom files for scalastic 2.10-0.90.10 [1]  appear to have 'classifier' sources, but I can't seem to get sbt to resolve them.  I'm attaching a full reproducible example below:

Is 0.90.10 not compatible with scala 2.10.3 and sbt 0.13.1?
