Description

I have a multi-module build which uses a plugin that generates code (xjc). The directory is added to the compile source directories.
With 2.13, this directory is by default scanned by checkstyle - but I want to exclude this.
It seems, that setting sourceDirectories doesn't have any effect for the child modules.
Is this even the right approach to exclude a source root?

Attached is an integration test. It just uses build-helper-maven-plugin to add an additional source folder.
The parent pom configures sourceDirectories to be just ${project.build.sourceDirectory}. I would have expected, that checkstyle doesn't find any violations, as src/generated/java shouldn't be checked.

I think, it's related with the change MCHECKSTYLE-70.

It works with 2.12
