    Betreff: RE: WAR-Plugin: Manifest and <optional>true</optional>  
not working :-/
         An: Jörg Schaible <Jo...@Elsag-Solutions.com>

Hello,

thank you. This article helped me to solve the problem.

But what comes into my mind is the question of having a mixed mode.
Some Jars in the EAR for all Wars and some specific Jars into WEB-INF/lib.
Could be helpfull to  some Classloader Issues.
I asumed, that setting the optional flag to a pom would transitive be
maped on the containing artifacts. But what the MavenProject Class does in the
getArtifacts Method is passing back each artifact of the pom without
having the optional flag to be set to true though they should inherit this
from the POM where theMavenProject has them from. With using scope
provided it works though. Then the artifacts are not being passed back
on method project.getArtifacts().

In my opinion it would make it easy to apply the optional value to the
pom child aswell. This way you could add a POM (and the transient
deps) as optional but have jars being placed in WEB-INF/lib aswell.

The way I solved it now with the help of the Article, you can have
either all or
none.

Or am I missing some Architectural Issues of maven at this point. I am not
too dep into maven yet.

Thank you for your help. Now I can move on :-)

Regards,
         Alexander
