I would like the maven checkstyle plugin to print the suppressions that need to be added to the suppressions file to make the checkstyle pass.
I think there's a flag (-g) to do this in the checkstyle CLI, but not sure how to do this in the plugin.
Maven checkstyle doesn't support that option right now.
I would request it on their issue tracker at https://issues.apache.org/jira/projects/MCHECKSTYLE/issues/ .
