Well, actually you *can* have group1:foo and group2:foo as war dependency, 
because the plugin will then prepend the group name to the jar in the war 
file. Don't know for other plugins that collect the dependencies, but Maven 
cannot and does not require unique artifactIds. However, it's better not to 
force this situation with artifacts from the same project. Therefore I am 
with James changing the artifactId to match the package name.
