That's discouraged by Maven central: https://docs.sonatype.org/display/Repository/Central+Sync+Requirements
It's understandable, too. Once an artefact's version "goes central", it will be published forever. On the other hand, the Sonatype repository may be subject to change (both the Sonatype URL's *and* my choice to actually use Sonatype). So I'm guessing, in order to get latest releases AND snapshots, you'll have to manually set up the Sonatype repository in your workspace, for now.
