Why doesn't ivy resolve my dependencies?

I have this dependency declared:

<dependency org="or开发者_运维技巧g.jboss.jbossas" name="jboss-as-parent" rev="6.0.0.20100216-M2"/>

And it just fetches the pom. Other dependencies are resolved just fine.

I'm using ivy 2.2.0 rc1 and ant 1.6.

If you take a look at the pom : http://repository.jboss.org/maven2/org/jboss/jbossas/jboss-as-parent/6.0.0.20100216-M2/jboss-as-parent-6.0.0.20100216-M2.pom

then you'll see the line

-packaging -pom- -/packaging-

In maven this means it's a pom project (as opposed to jar or war) and so doesn't have any jar to go with it. These are usually used to group dependencies / perform functions other than supplying a resource.

Hopefully that makes sense.
