Description

Currently aggregator Mojo (annotated with @Mojo(aggregator=true, ...) ) are used to define Mojo whose goal whould be called directly, not bound to a lifecycle phase.
This is the case for release:prepare / release:perform for exemple.

I would be good if such aggregator Mojo ware also executed only once when part of a lifecycle. Currently we have to specify <inherited>false</inherited> in the pom.

It would comply to the principle of least surprise because it seems every doc I found just say something "like these Mojo will be executed only once", and do not specify "in the case of direct invocation".

I first reported this behavior on the mailing list: http://maven.40175.n5.nabble.com/Make-custom-plugin-executed-only-once-in-multimodule-inherited-false-aggregator-td5921630.html

This JIRA may be related to improvement in the lifecycle ( MNG-5665 ) as suggested by rfscholte
