Reactor builds fail due to erroneous cycle in project sorting which does not consider versions

      Description

      Just to officially track the reason why the parent POM maven-plugins currently excludes the maven-project-info-reports-plugin from the reactor:

      [INFO] Scanning for projects...
      [INFO] ------------------------------------------------------------------------
      [ERROR] BUILD FAILURE
      [INFO] ------------------------------------------------------------------------
      [INFO] The projects in the reactor contain a cyclic reference:
      Edge between
        'Vertex{label='org.apache.maven.plugins:maven-remote-resources-plugin'}'
      and
        'Vertex{label='org.apache.maven.plugins:maven-project-info-reports-plugin'}'
      introduces to cycle in the graph
        org.apache.maven.plugins:maven-project-info-reports-plugin -->
        org.apache.maven.plugins:maven-remote-resources-plugin -->
        org.apache.maven.plugins:maven-project-info-reports-plugin
      

      It appears the ProjectSorter does not take versions into account, i.e. there is no cycle in a multi-module scenario like this:

      parent:1
      - plugin-a:2.0 which uses plugin-b:1.0
      - plugin-b:2.0 which uses plugin-a:1.0
