One "in and out" to learn is that your distinction of "internal" and

I found it here:

Is the term "external repository" not valid?
Also, I just wanted to be a good Maven citizen and take a load off
Central, if that wasn't too hard to do.
Again, as a single developer, it isn't possible to take load off
Central
(or mirrors) because you always need to download artifacts at least
once. And unless you do the things I said above, you never need to
download artifacts *more than once*.
I guess I was thinking of SNAPSHOT dependencies, in which case Central
would be queried on every build, right? But then, I never depend on
SNAPSHOT versions of external artifacts, so yeah, it wouldn't make
much difference.
But perhaps the most important reason is that I need to deploy
customized versions of some Maven plugins.
There are a couple I'm using on Central that are buggy, and might
not be updated for awhile, so I need to
deploy and use versions that have the bugs fixed. It's not clear to
me if I need a repository manager for that,
or if I can get away with the non-managed repository I have now for
deploying project artifacts (and the site).
You don't need a repository manager for this. You can deploy these
artifacts to your own remote repository.
Okay, let me make sure I understand this. Say I've got a main artifact
and a customized plugin that it depends on. I can configure the plugin
to deploy to my own remote repository by adding the repository info to
the plugin POM's <distributionManagement>. So now the plugin is
available in my repository. But here's where I get a little
confused... How does the main artifact know how to retrieve the
deployed plugin from my remote repository? Do I simply add the remote
repository URL to the main POM's <pluginRepositories>? (This seems to
be discouraged: "I have yet to hear a convincing argument for doing
so" [1]) Or should I add it to <repositories>? Or somewhere else?
Thanks,
Trevor
