Hi there. I'm currently setting up Hudson to push artifacts to my Nexus repository upon succesful builds. Unfortunately I am having some trouble with getting Hudson to deploy using Nexus groups.

I have two groups, upbeat.nexus (private) and public.nexus (public). I've set up the associated repositories in Nexus already. Here's my settings.xml:

<settings>
    <mirrors>
            <mirror>
                    <id>upbeat.nexus</id>
                    <mirrorOf>*</mirrorOf>
                    <url>http://localhost:8099/nexus/content/groups/upbeat</url>
            </mirror>
            <mirror>
                    <id>public.nexus</id>
                    <mirrorOf>*</mirrorOf>
                    <url>http://localhost:8099/nexus/content/groups/public</url>
            </mirror>
    </mirrors>
    <profiles>
            <profile>
                    <id>upbeat.nexus</id>
                      <repositories>
                        <repository>
                            <id>upbeat.central</id>
                            <url>http://central</url>
                            <releases><enabled>true</enabled></releases>
                            <snapshots><enabled>true</enabled></snapshots>
                        </repository>
                      </repositories>
            </profile>
            <profile>
                    <id>public.nexus</id>
                      <repositories>
                        <repository>
                            <id>public.central</id>
                            <url>http://central</url>
                            <releases><enabled>true</enabled></releases>
                            <snapshots><enabled>true</enabled></snapshots>
                        </repository>
                      </repositories>
            </profile>
    </profiles>
    <servers>
            <server>
                    <id>upbeat.nexus</id>
                    <username>build</username>
                    <password></password>
            </server>
            <server>
                    <id>public.nexus</id>
                    <username>build</username>
                    <password></password>
            </server>
    </servers>
    <activeProfiles>
            <activeProfile>upbeat.nexus</activeProfile>
            <activeProfile>public.nexus</activeProfile>
    </activeProfiles>

In Hudson, when setting the "Deploy artifacts to Maven repository", I need to specify the repository URL and the repository ID. I've set the repository ID to "public.nexus" but if I set the URL to http://forge.upbeat.no/nexus/content/repositories/public and the ID to public.nexus I get the following error:

Any tips on how to deploy to a group so I don't have to specify (in Hudson) whether or not I am building a snapshot or a release version, and instead have it look at the version-tag in the pom to automatically place the artifact in the correct repository?
