No. Everything happens locally you don't have to deploy anything.
If the JAR is providing functionally separate code then you put it
in another module. Otherwise then just compile the classes and put
them in your WAR and just use one project.
The JAR is only providing build dependency code. i.e. kind of like
xerces-api vs xerces-impl.
Yep, I put it in another module. So how do I now put them both
(webapp and code modules) together into a WAR?
You just specify it as a dependency. You need to read a bit of the
website and look at the WAR plugin.
Dependencies pull from a remote repository. I don't want to pull
from a remote repository, I want to pull from modules themselves
(locally), into a combined WAR.
I've been reading the documentation for two days, and have not seen
anything that does what I am asking, which is why I am asking. If
you know where the documentation is that tells me what to do, by all
means point it out. :)
Read the getting started guide. There's an example of the WAR at the
bottom. The website is abysmal and I apologize as it took me 5 minutes
to find it.
Yeah, I agree, it can be daunting to navigate now and then. Anyhoo,
that is the section of documentation that I've been basing everything
off of. Unfortunately, I had a typo in my dependency. I had copied the
"junit" dependency, and forgot to take out the scope of "test". So, it
wasn't sucking in the dependency JAR. So, apparently dependencies can
be automatically retrieved from the local modules, rather than going to
a repository. That is good. :)
Thanks.
The WAR plugin, as far as I've learned, is automatic, and works when
you specify a packaging model. My parent has a packing model of
"pom", my webapp has a packaging model of "war" and my code has a
packaging model of "jar".
If so, that's more complex than ant, for this set of
functionality. If not, how do I go about doing it?
Okay, so I've got two sub-projects now. How do I get the webapp
to build a WAR with the JAR from the code of the other sub
project? And, can I do it without deploying the JAR to a
repository?
And hey, I agree with enforcing the "architectural integrity"
concept, as long as it is not too restrictive. I'm going to have
to wait and see if it's as restrictive as it seems. It could
just be me at this point. But, any help you could give to
convince me of your stance, would be appreciated. I do like
"simple". I try to write my code simple, and I want my builds to
be simple, and maintainable as well.
Thanks.

Yes, it definitely is simpler in some ways, but ends up being
more complex, and less intuitive in many other ways. Kind of
like a Mac in comparison to Windows. Mac is so dumbed down it
becomes difficult to use to get the job done, in many other
ways. I found ant a lot easier in many ways. The learning
curve for ant was extremely minimal. I suppose I have to use
maven, just for it's dependency management, but I sure don't
like the structure it uses. :(
It's not more complex as the premise is that composition trumps
a big globular build. It is intentional and in the long run will
prove far more useful. Based on feedback from hundreds of users
over the years this has been the overwhelming opinion. We
enforce this architectural integrity from the get go.
So, how do I go about doing it then, with multiple projects?
Do I have two copies of everything? Do I make one module
depend on the other, so that every time I want to deploy, I
have to either install the dependency JAR into the local
repository, or a remote one, so that the webapp has access to
it? i.e. If I update the one project, that has the class files
and such, how is the webapp project going to know about it?
It kind of upsets me, because a couple years ago, I
specifically combined two projects that were really one
project, because ant has the ability to make different jars and
such. I did it because it was "simpler", and now maven is
making it more complex. :( Okay, I'm done pouting. :P I'll
have to see if it's worth it.

No, it isn't. That's the suggested way to do it.
to be a better way than that. Isn't there? I thought maven
would at
least have the functionality of ant.
Of course, Maven can do anything that Ant can do: Just use the
maven-antrun-plugin and create an Ant script that can be
launched from
Maven. The funny thing about Maven is that it enforces you to
work
structured. That implies, in particular, to think and work in
modules.
Once you get used to it, you'll soon learn that it simplifies
things.
At least, my Maven scripts are typically much simpler and more
easily
understood than my monster Ant scripts.
