Isn't it already possible to "extend" the lifecycle by simply putting
plugin + execution into root pom?
Main problem for me is that currently packaging == type == lifecycle,
otherwise one could simply have an "empty" lifecycle + whatever
packaging and simply bind anything you want tin pom.xml e.g.
<project>
<packaging>jar</packaging>
<lifecycle>empty</lifecycle> (would default to packaging if not
given, where empty is just a lifecycle with no mappings)
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<executions>
<execution>
... define all your custom bindings here ...

Hi all,
Reviewing and trying to follow Martin's thread about JPMS I thought about
the old issue that our build pipelines (plugins chain) is very hard to
customize.
Guillaume added the priority case but the clean solution proposed
originally was to define custom lifecycles (to add frontend, docker builds
for ex) - more or less a custom AbstractLifecycleMappingProvider.
I wonder if we shouldn't extend .mvn/extensions.xml (or root pom
<extensions> block) to support to define custom lifecycle mappings there
and potentially explicit new "types" too which would be great for Martin's
work since it would allow to avoid undefined types and implicit jar mapping
in a "strict" mode (to detect typos for ex since it must become open).
So proposal is to extend extension to get more configuration - and coded
extensions can indeed plug themselves there.
The main challenge seems to be to re-evaluate the mappings but looks doable.
High level it is more or less "let the pom/.mvn inject maven components
without coding/by declaration".
Hope it makes sense, let me know if it is worth investigating more or if
the idea is too particular to my old needs.
Best,
Romain Manni-Bucau
