proxied repositories -- plugin question

[Eric Miles]

I have a managed repository that I intend to use as a proxy for several
remote repositories.  I'm doing a test and can't get the proxy to
resolve a plugin dependency to save my life.  It will however resolve
regular dependencies to same remote repository.  I am attempting to
proxy the Dev Java Net remote repoistory.

Here is my pom:

I have no problems resolving and proxying quickr and j4j dependencies,
but I get the following error for the jaxb2 maven plugin:

$ mvn clean package

Any suggestions?  Thanks in advance.
