[MPMD-363] aggregate-cpd-check doesn't work on large projects

[jira-importer]

Delany opened MPMD-363 and commented

I'm having some trouble with the aggregate-cpd-check goal in a large project. The reactor build passes when it should fail. I know there are violations since cpd-check fails a couple of modules individually. But on another smaller project aggregate-cpd-check correctly fails the build.

I'm not able to share these projects, but I can share some logs. Here are the relevant snippets starting after the first "[DEBUG] Configuring mojo 'org.apache.maven.plugins:maven-pmd-plugin:3.20.0:aggregate-cpd' with basic configurator -->"

WORKING CORRECTLY (finds cpd violations):

Where are all the "Searching for files in directory"?

The only noticable difference between the configuration is the enormous reactorProjects property (500 items).
