Starting with an explanation of what you are trying to accomplish rather
than with what problem you are experiencing, usually makes the problem
easier to solve and makes the advice you get actually helpful.
What are you trying to do that makes your requirements so non-standard?
If you are just trying to separate the war from the code, this is pretty
standard and a good idea.
You make 2 projects, one to make the jar and another to make the war.
Both become trivial examples of maven projects and do not require any
crazy plug-in configurations.
The war has a dependency on the jar.
If you want to install the jar separately from your war(jar not included
the war), make the jar dependency in your war POM as scope "provided".
Maven will not put any jar contents in the war file and will leave it up
to the Servlet container to find the classes.
The jar is nothing special and all of the components will be where they
are supposed to be and you will have no trouble when you try to run your
app.
http://blog.artifact-software.com/tech/?tag=maven has some articles that
I wrote on making multi-project application work with Maven with this
sort of separation of libraries from war configuration.

- This should contain all the class files and dependencies of war
project. However dependencies should be copied under lib folder of
this jar and should not be in unpacked form.
I hope you are aware that this conflicts with the jar-specs. The
classes inside the lib/*.jars won't end up on the classpath, which
makes this jar useless.
I'd strongly advice you not to solve it as you described.
thanks,

Hi,
Thank you for your response.
I am already aware about these two parameters.
I don't thing 'archiveClasses' parameter will be of any help in my case.
I had tried to use 'attachClasses' initially but I could not figure
out how to pull war dependencies (and that too in a lib folder) in
the jar file which will be generated by setting this parameter to true.
So I have no solution for my problem yet.
Thanks

Hi,
have a look at the following parameters of the manve-war plugin:
- archiveClasses[1]
- attachClasses[2]
I suggest *not* to use the maven-assembly-plugin in this case. It'll
make
things over-complex.
thanks,
Robert
