Hi Anders

Can you provide some arguments to this statement?
We currently recommend all our projects tech leads to add to their top level project pom.xml the repositories they use (each individual project tree usually has 3 repositories: releases, snapshots and 3rdparty). Since the projects are worked internally only, this eases new developers and developer rotation in projects. Our recommendation derives mainly from this blog post from the Sonatype blog: http://www.sonatype.com/people/2009/02/why-putting-repositories-in-your-poms-is-a-bad-idea/ If there are aspects of this approach that we are not aware of, it would be great to see them discussed.

Thanks for your time!
Best regards
Joao Silva

You should NOT declare repositories (or plugin repositories) in a
corporate pom. That should be handled in settings.xml.

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.
