The key for me getting play to use my nexus repository rather than mavenCentral was to name my nexus repository in dependencies.yml as "mavenCentral":

repositories:
    - mavenCentral:
        type: iBiblio 
        root: "http://nexus.mydomain.com/nexus/content/groups/public/"
        contains:
            - com -> *
            - org -> *
            - play -> *
