What I do is have a top-level POM like (see below), and then I have my
top level project POMs reference that (see further below). This may not
be the best example, as I am still in the process of building the
infrastructure, but
1. I put the Parent POM in its own place in source control and I
manually deploy it with Maven when I make changes.
2. You need to do this before creating any Project POMs that reference
it because they should reference it via Maven and not the file
system - if you work in a large company you will soon discover why.
3. There is of course a bootstrapping issue because now the project
POMs need to know how to find your Repository Manager, which is why
I include that information in the top level (Corporate) POM so
people can use it as a reference.
4. As you may gather I am using Sonatype's Nexus as a Repository Manager.
5. We are still developing our corporate repository infrastructure so
the content of the Corporate POM will evolve over time as our
corporate governance and policies are better codified.
Does that help?

Hi Maven Team,
I am trying to find out what is the best way to define company specific
GLOBAL POM.XML. Which each team can inherit it in EACH Projects.
Can some one provide me guideline on that ? Is that going to be profile or
just simple POM.XML ? And how to inherit that. Please provide me guideline
to implement it. As this is very critical before we implement all projects
with MAVEN.
Thanks,
Daivish.
