Hi Orion,

I already fixed the problem here :).
> - maven-antrun-plugin needs to list ant-launcher in its dependencies
I'm pretty sure that this is the right answer. But it should be done not on 
the RPM side but on the Maven side i.e. adding ant-launcher to maven-ant-
plugins dependencies in maven-ant-launcher pom.xml

Alex
