The code has undergone major refactoring in the past months, so any pointer you could find would be useless imho. Basically, focus on impl/maven-impl and impl/maven-core, the other subprojects are APIs or compatibility and should rarely be touched. In your case, you're willing to alter the main model, which is located at
https://github.com/apache/maven/blob/master/api/maven-api-model/src/main/mdo/maven.mdo A bunch of classes are generated from this file, just rebuild the whole project. However, before trying to modify the model, I wonder if you can try something like the following in the child: <dependencies combine.self="override"> ... </dependencies> This attribute is currently only used in XML configuration (so mainly for plugin config), but maybe it would make sense to reuse it. And first, I'd also investigate the <scope>none</scope> idea, as this is supposed to work afaik.
