Override MavenSimpleLogger in Custom Maven Plugin

I'm writing a maven plugin and a dependency makes a cast like so:

ch.qos.logback.classic.Logger logger = 
      (ch.qos.logback.classic.Logger)LoggerFactory.getLogger("ROOT");

which fails with this error:

org.slf4j.impl.MavenSimpleLogger cannot be cast to ch.qos.logback.classic.Logger

I've tried adding direct dependencies to logback and moving dependencies around in my pom but I can't figure it out.

Any ideas?
