Hi,
This is perfectly normal operation. I'll explain what happens,
since it took me some time to see the problem :)
You're running 'mvn compile'. That means that no .jar, .rar, .ear,
or any other artifact, is being generated.
The ear plugin requires an artifact. If you're running a reactor build
(from RootProject), maven checks the projects in the scope to see
if xmpp-... is present, when it tries to resolve the dependencies
for the ear project.
It sees that it exists. Next, it tries to use the target/classes
directory as the 'artifact' (${project.build.outputDirectory}).
That's not present, since your rar project does not contain
any sources, right?
Then it tries to find the artifact using the normal dependency resolution
mechanism (local repo, remote repo's).
Conclusion: just run 'mvn install' or 'mvn package'.
