One solution would be to add an attribute on the model specifying a list of
fields that should not be inherited.
{code}
{code}
However, if you're writing a POM that will be consumed, maybe a better solution
would be [MNG-5102|https://issues.apache.org/jira/browse/MNG-5102].

Garret Wilson commented on MNG-7562:
I [asked about this on Stack Overflow|https://stackoverflow.com/q/73239332],
and someone [suggested|https://stackoverflow.com/a/73983784]
{{child.licences.append.path=false}}, which is apparently a mechanism
introduced in MNG-6059 (building on MNG-5951) and documented briefly in [Maven
Model Builder|https://maven.apache.org/ref/3.8.6/maven-model-builder/]. But
this mechanism doesn't seem to prevent inheritance—it only seems to prevent
appending a path to the inherited value, unless I'm reading it incorrectly.
