> ModelBuilder is component building models (POM + interpolating + parent
> inheritance and many many more things), but it should not rely that built
> model "was validated", as it MAY NOT been validated: for "furthest" models it
> builds, like a parent of a some-level-dependency we use MIN level of
> validation (minimal validation).
> Still, while the model builder builds, it relies on several aspects of the
> model, and it should ensure that the "output" (built model) is correct. Model
> Builder hence must be changed in way, that IF it detects any issue _during
> building_ of the model, and IF it appears with even slightest possibility
> that it cannot deliver "correct output", it must add WARNs to model building
> result with proper messages.
> One typical case is when model building injects activated profiles (as they
> can deliver properties and extra plugins and what not) and activation code
> detects a "problem", like for example duplicated profile IDs being used (this
> IS catched by validation, but not on MIN level!), hence, model builder cannot
> guarantee that built model IS correct.
> This change is really only to make Maven emit WARNINGs if project being built
> has some "far POMs" (like parent pom of a dependency of a first level
> dependency, as in reproducer). If model builder cannot be "100% sure" it
> built model correctly, it should be reported. Moreover, WARNs of model
> building result were simply neglected so fat (lost). Having warnings like
> these would reveal "invalid parent POM" early, as it is case in issue
> MNG-8131 for example.
