    // MAVENAPI FIXME: the DAG used is NOT only used to represent the dependency relation,
    // but also for <parent>, <build><plugin>, <reports>. We need multiple DAG's
    // since a DAG can only handle 1 type of relationship properly.
    // Use case:  This is detected as a cycle:
    // org.apache.maven:maven-plugin-api                -(PARENT)->
    // org.apache.maven:maven                           -(inherited REPORTING)->
