ComposerCollector doesn't allow to check exclusion from one of the packages

      - Vendor

In the Vendor layer packages I have the sebastian/comparator package specified, which is ignored by ComposerCollector. My guess is that this package uses autoload/classmap in composer.json instead of psr-4.

Hello, you are correct, it uses classmap to load the files. It not working is expected documented behavior. Straight from the composer collector documentation:

The composer collector allows you to define dependencies on composer require or require-dev packages that follow PSR-0 or PSR-4 autoloading convention. 

I would suggest using DirectoryCollector over the package's src dir instead.
