Description

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.
