Problem with build a portlet component

Hi,

I have a problem to build a portlet component.
I have a portlet A with the pom-packaging exo-portlet. I can build it.
I have a portlet B which has a dependence to Portlet A. I see by building this component, that maven lookup for a package of Portlet A as jar file instead of exo-portlet or war file. I have a work-around, I copy the package war file of Portlet A  to a jar file in the maven repository.
How can I resolve this problem ?

Thanks
Abdel
