--------------------------------
Resolution: Fixed
> ProjectBuilder api and ModelBuilder enhancements
> ------------------------------------------------
>
> Key: MNG-8120
> URL: https://issues.apache.org/jira/browse/MNG-8120
> Project: Maven
> Issue Type: Improvement
> Reporter: Guillaume Nodet
> Assignee: Guillaume Nodet
> Priority: Major
> Fix For: 4.0.0-beta-5
>
>
> The project builder uses multiple caches in the
> {{DefaultProjectBuilder.BuildSession}}:
> * the {{modelPool}}
> * the {{parentCache}}
> * the {{transformerContextBuilder}}
> * the {{modelCache}}
> The responsabilities are not clear, and the project builder needs to pass
> objects to the model builder without a clear API. A {{ModelSession}}
> interface should be provided by the {{ModelBuilder}} so that requests can be
> grouped and data cached correctly.
> This {{ModelSession}} becoming a public API, it could be stored and made
> available through the {{Project}} object, thereby becoming available to the
> {{DefaultConsumerPomBuilder}} which needs to re-load models _inside a given
> model session_ (so as to access cached parents for example).
> The {{transformerContextBuilder}} which is used for raw/build POM
> transformation, needs to access already loaded models and eventually load new
> models.
