How do you get output from a maven plugin in Eclipse when using the m2e lifecycle-mapping?

I'm unable to get any output from the custom java class (SchemaGenerator) to output in the Eclipse Maven console. Is there a way to do this? The class currently uses sys out and sys err, which appears in the output when using mvn from command line.
