Maven warning about local scope 'null' ?

[Jason Dillon]

Anyone have any idea why this warning is being issued durring  
car:install-modules?

<snip>
[WARNING]
        Artifact org.apache.geronimo.configs:j2ee-deployer:car:2.0- 
SNAPSHOT retains local scope 'null' overriding broader scope 'compile'
        given by a dependency. If this is not intended, modify or  
remove the local scope.

I don't remember seeing this before.
