Skipped scalastyle: Channel beta not found for scalastyle, available channels: ["stable"]

[filipesperandio]

Ah, right. beta is not available in the CLI, though, this version is already the latest on dockerhub, meaning the CLI gets it on the default/stable channel.

On codeclimate.com it is going to be in beta for while.
