[MNG-8214] Allow extension of the model classes being generated with model.vm

[jira-importer]

Konrad Windszus opened MNG-8214 and commented

The model.vm being used with Maven 4 models generates immutable classes with builders. The generated classes cannot be extended easily because

1. the builder's constructor is having default access instead of being protected (

   maven/src/mdo/model.vm

   Line 409 in e335f95

   Builder(boolean withDefaults) {

   and

   maven/src/mdo/model.vm

   Line 427 in e335f95

   Builder(${class.name} base, boolean forceCopy) {

2. the classes constructor doesn't take a builder as argument (therefore the subclass cannot leverage most of the functionality currently encapsulated by the Builder)
