[ http://jira.codehaus.org/browse/MWAR-9?page=comments#action_72277 ]
Wonne Keysers commented on MWAR-9:
--
Compile time dependencies can be excluded from the WEB-INF/lib by using the
true flag. However, this currently does not work
recursively.
For example: if the war has a dependency on A.jar, but A.jar itself s dependant
from B.jar, putting the A-dependency optional excludes it from the war (yet it
includes it in the manifest), but B.jar is still included in the WEB-INF/lib.
If the optional flag would be working recursively, I think the solution would
be complete?

> I noticed that when I build a WAR, I get a gigantic WEB-INF/lib with all my
> deps. This is fine for a default but maven should also support "skeleton"
> WARs which will be packaged within an EAR. We have EARs which package 3-4
> WARs each and to have the deps duplicated within each WAR means we cannot
> have shared data (since the classes are loaded within each WAR's classloader,
> rather than by the parent EAR's classloader). It also means 80MB EARs! :-)
> It seems like two things need to happen:
> 1) Add a "skeleton" flag which prevents copying any dependencies to
> WEB-INF/lib.
> 2) Instead generate a META-INF/MANIFEST.MF which has a Class-Path entry which
> lists the relative locations of the dependencies within the parent EAR.
> Fabrice has basically the same idea written down here. Starting with "- for
