Description

The recommendation at https://maven.apache.org/plugins/maven-checkstyle-plugin/examples/multi-module-config.html breaks down in projects that use the pattern more than once, e.g. for checkstyle/findbugs/PMD alike. I have boiled this down to a super-simple test project that defines a build-tools module, and in separate profiles declares each of these plugins with a dependency on that submodule. Activating any one of these profiles and calling `mvn validate` works fine, but as soon as you activate two or more of them the command fails with "The projects in the reactor contain a cyclic reference".
