Hi all,
I'm using the pom snippet shown above but I would like to have some
dependencies prefixed and some others not.
Is this doable with maven or will I have to write the MANIFEST.MF file
myself ?
Regards
Paul

Hi,
I can't give you the definitive answer but the maven-jar-plugin [1], the
maven archiver [2] and the plexus archiver [3] are places to look at.

Hi Wayne,
Thanks for your answer.
I'l be glad to contribute such a fix. Could anybody with needed maven
knowledge point me to the place where it could be implemented.
Regards

In fact it does have to do with JEE packaging. I do not use WebSphere or
WSAD but Glassfish.
When you package a JEE application (ear packaging) the ClassPath set in
the MANIFEST.MF file is important, so the packaging layout is.
EJB or WAR modules have to be at the EAR's root. The "lib/" subdirectory
contains librairies.
You can have a module (EJB-JAR, WAR, RAR) that needs some JARs from the
lib/ directory _and_ some others from the EAR's root.
The EAR plugin lets you arrange files easily but managing MANIFEST.MF
files when there's several modules in you application is a tedious task.
Here comes my question ;)

I built them manually today because we need to keep coding/testing. As our
application packaging will not evolve the sooner, I'll check back on this
issue later. It's in my inbox :)

Why? I'm curious because someone at work also wants to do this, and I
don't see what would be gained by it.
Does it have anything to do with WebSphere or WSAD? (That's what this
team is using, and I'm trying to sort out what things they really
*need* vs. what they're trying to do just because that's the way WSAD
has always done it.)

At the moment I think you'll have to maintain the MANIFEST.MF file
manually, but I'd love to hear otherwise...

As far as I know, you'd need to write the MANIFEST.MF file yourself.
"Some prefixed, some not" is not functionality that is currently
available. You are welcome to add it and contribute it back, of
course.
