If there are specific suggestions or questions about the maven blog
articles (from anyone), I would be grateful to have them.
They were written rather quickly to explain a technique that we found
useful. People may have to read more than one of the maven articles to
get the gist of what we do.
Some of the more experienced and knowledgeable people in this forum have
some reservations about our approach so I would hesitate to propose it
as a "Best practice" but it does address the problem that you are facing
in a way that works in a team environment (small team)
and achieves the objects that we sought
- faster maven build (install,deploy),
- small wars (only our code),
- easy deployment (fewer shared libraries)
- shorter and simpler pom dependency specifications and
- complete management control over versions of third party libraries.

Thanks for your time
I have started with making red5 "provided" but the build failed since
necessary classes were not found.
May be is there any way to provide dependency before build ...
If not I will try to create optional dependency and another one subproject,
not sure if it will work.
I believe the blog article would be better if you can extend it a little
bit and improve the formatting. Actually I can't se how it can help me :(
Thanks for the help :)

If you need consulting to move forward, there are others here that do
Maven for a business and can help you better than I can.
Have you tried making the red5 scope "provided".
What does this do to your build?
Does it get eliminate the red5 classes from your jar so that it only
appears in the assembled war as a resource?
To make life simpler, remove all code from the war project and put it into
a separate project that makes a jar that the war depends on.
This will make it clearer when you need red5 to compile your code and when
you need it to build a deployable war.
It will have scope "provided" as a dependency in your jar project.
Do you have specific questions about my blog articles on Maven and
aggregation jars?

So, as far as Maven is concerned, Red5 is scope "provided".
You want it to reference it for compiling but should not put its classes
in the jar or war since you are going to sneak it into the package
without
Maven noticing.
Pretty standard problem. We make a lot of aggregation jars that are used
in the same way.
http://blog.artifact-software.com/tech/?p=121 describes how we handle a
similar need to produce skinny wars that use libraries in Tomcar/shared
or
tomcat/lib to avoid copies of the same code in multiple jars. Our LMS
project has over 80 Maven projects that produce a variety of jars and
wars.
Many of these share the use of large libraries such as CXF, Spring and
Apache commons that can be shared through Tomcat's classloader rather
than
duplicated in each war.
There are some other notes about Maven on our blog that you might find
interesting.
I would prefer an installer to get the shared libraries into tomcat/lib
but that is another issue.

Here is the structure:
"Openmeetings Util" project has compile time dependency "Red5 server"
Almost all other projects are dependent on "Openmeetings Util" and "Red5
server" (compile time)
But When I'm creating war file in "Openmeetings Web" project I need to
remove "Red5 server" and all it dependencies from the WEB-INF/lib folder
since all these jar files will be placed into tomcat/lib folder.

Can you describe the "forking" Maven problem in more detail.
What does it do that you don't want and what does it not do that you
need.
Is there anything about your build that is different from the
thousands
of projects that use Maven to build Tomcat applications?
Have you looked at using Maven to build an installer with izPack.
This will let you use Maven to build the components and use the
maven
izPack plug-in to build a user-friendly deployment tool that lets a
system
admin install all of your components in the "right" places with the
required permissions, initialization, etc. that may be required.

I was hoping there is a way to avoid specifying parent version in

But it seems to be "Maven way" :)
Maybe you know how to manage project forking? My projects are being

Well, though I agree Maven isn't designed to be an end-user

using it

IMO, if what you're trying to do is building your product from
some
sources
and binaries, then Maven can obviously do it.
If what you need for production is an installer, then creating
an
installer
using izpack is indeed a good idea, but you would just build
that
installer
during your Maven build (http://izpack.codehaus.org/
izpack-maven-plugin/e.g.).
You seem to actually have two kind of phases:
* the first one, typically compile and package your sources
using
binaries
coming from a repo manager (be it a corporately managed one,
or
directly
from Central)
* the second one, creating the end-user distribution, is
typically
done
with Maven using maven-assembly-plugin.
Don't hesitate to ask questions, because I don't think we've
gone
so
far
until now to understand your building steps.

Thanks Ron,
I'll take a look at it, but I'm afraid distribute
application
in
"partially
compiled state" is not an option.
Currently it works out of the box and this is the requirement.
Will try to study maven and postpone the migration for now

You might find that your life will be a lot easier with
IzPack
as
the
tool
to create your installer.
It will allow you to package up your maven artifacts with
other
resources
into different OS-specific installers that can be distributed
easily.
It supports install time execution of your procedures so that
you
can
start RED-5 or execute the flex processes required to build
and
install
the
Flash assets.

Red5-server is "custom tomcat" (zip/tgz with scripts,
libraries,

etc.).
We need to pack it in our distribution, not sure if it can

done
"Maven

2) tgz contains flex based Flash compiler with all

IIUC, your project openmeetings depends on red5

About your questions:
1) Not actually a Maven issue, but you seem to think the
way
to
go
it
to
build that dependency. As the project is ASLv2, you would far
better
make
sure/ask it be uploaded to Maven Central. Then just just
the
<dependency>
in a normal way/
Maven is actually very straightforward if you follow the
Maven
Way
(yeah,
sounds like a sect somehow, you may think ;-)).
2) Once again, what does contain that tgz? If it contains
jars
and
so
on,
then forget about downloading and decompressing it during
your
buil.
Or
you're gonna a world of despair. Just upload those libs
under
some
sensible
coordinates in a corporate (or better, in Maven Central if the
project
is
OSS), and add the dependency.
Please ask more questions/give more precisions if you want
more

Hello All,
I'm new to maven and not very familiar with all its
plugins.
I need to move project [1] from ant+ivy to maven
The problems are:
1) this project is build on top of [2] maven project (we
need
the
exact
structure and all libraries from this project) *[first
problem: i
don't
know how to do it]*
I did it using ant as follows:
a) using SVN download the project sources
b) build it using maven
c) unpack artifact and use it's structure in my
build
Currently this project was moved to git and I was hoping
it
will
be
possible to using maven scm:git for this, not sure
how :(
2) this project need to download tgz file with required
framework,
extract
it somewhere and use extracted file to perform the
build
*[second
problem:
is this possible?]*
Any help is highly appreciated
