I personally do more as you do.
I have team-wide "super-POMs" I have a primary one that has basic
url, issue management, etc. type settings. Then I have a "core" POM
with common dependencyManagment section to encourage use of the same
versions of Jar's to prevent incompatibilities, as well as common
reporting configuration. Then I have a "webapp" parent POM that
specifically states the provided dependencies for webapps to be
deployed to our target server, as well as webapp specific stuff, such
as setting <finalName>${project.artifactId}</finalName> to remove the
version number from wars, and <wtpVersion>1.0</wtpVersion> for the
Eclipse plugin.
For multi-module project, I have an aggregating POM that defines the
modules, but each module uses the appropriate "super-POM" as its
parent, not the aggregating POM.
I've found this to work better for us. But I too have been wondering
what the reasoning for the pattern of using the aggregating POM also
as the parent POM is...

Hi all,
this is kind of a best-practise-question about your habbits of using
the concepts of multi-project-super-pom.
First of all, are there distinctive terms commonly agreed upon for
each of those concepts?
Second, those two ways of using POMs appear to me to be orthogonal to
each other, really. Parent POMs are used to define common
characterisitics for a group of projects. Multi Project POMs on the
other hand aggregate modules belonging to a greater project. I usually
have the habbit of defining two diffent poms for multiproject
situations. e.g.:
/multiproject-pom X
-parent-pom Y
-module A / pom A (parent pom: Y)
-module B / pom B (parent pom: Y)
In most examples found though (e.g. in maven's own sources themselfs)
typically multi project poms at the same time are used as parent poms
for those modules they aggregated.
So, what I can't get my head around yet is, is it just a matter of
habbit or taste to combine those two usages in just one POM? or am I
really missing something important here, if I define two distinctive
POMs the way described above.
I'm thinking about this for quite a while now and any clarification
would be much appreciated.
