------------------------------------
Summary: Allow extension of the model classes being generated with
model.vm
Key: MNG-8214
URL: https://issues.apache.org/jira/browse/MNG-8214
Project: Maven
Issue Type: Improvement
Affects Versions: 4.0.0-beta-3
Reporter: Konrad Windszus
The [model.vm|https://github.com/apache/maven/blob/master/src/mdo/model.vm]
being used with Maven 4 models generates immutable classes with builders.
The generated classes cannot be extended easily because
# the builder's constructor is having default access instead of being protected
(https://github.com/apache/maven/blob/e335f95dfd11468bdf617421fd5e7093a727d1e1/src/mdo/model.vm#L409
and
https://github.com/apache/maven/blob/e335f95dfd11468bdf617421fd5e7093a727d1e1/src/mdo/model.vm#L427
# the builder's build method doesn't rely on generics. Instead an additional
constructor should be added which takes a parameterized builder object (like
outlined in https://stackoverflow.com/a/17165079)
