Maven + Jenkins not packaging war with jars

[Gandikota, Murthy]

Hi All
Using Jenkins 1.596, the jar files are not included in the WAR by maven which 
is given the following goals:
clean dependency:tree install -P component clover2:setup test clover2:aggregate 
clover2:clover
When I run maven on the command line the WAR is built correctly by including 
all the dependent jars. Also, when an upstream project invokes build, the WAR 
is built correctly. Can anyone figure out why this is so?
Many thanks for your help
