Herve Boutemy updated MNG-7991:
-------------------------------
Summary: refactor "aggregator" goal feature (was: refactor aggregator goal)
> refactor "aggregator" goal feature
> ----------------------------------
>
> Key: MNG-7991
> URL: https://issues.apache.org/jira/browse/MNG-7991
> Project: Maven
> Issue Type: Wish
> Components: Plugin API, Plugins and Lifecycle, Reactor and Workspace
> Affects Versions: 4.x / Backlog
> Reporter: Herve Boutemy
> Priority: Major
>
> aggregation was added in early Maven 2 stages with MNG-250, not really
> documented AFAIK
> there are multiple shortcomings found over time:
> * discrepancy between CLI and lifecycle use: CLI skips execution in
> sub-modules, but not lifecycle
> * forked lifecycle execution vs second execution in modules
> * sometimes, instead of executing aggregate goal *before* building modules,
> it would be useful to execute aggregate *after* building modules (to
> aggregate some results built in each module)
> notice that this looks also like the need for "execute at end" as found in
> install/deploy
> we probably need to better document what aggregate currently does and define
> what should be the target: perhaps refactoring will require new mechanisms
> that we won't call aggregator, like MNG-5665...
> edge case: aggregating reports for maven-site-plugin (launched by
> maven-reporting-exec, hence quite independent from associated reporting goals
> even if we expect some consistency between site reports and reporting goals)
