java artifacts are not being deployed to nexus

[KurtStam]

Our settings is pointing 'mvn deploy' to 'snapshots' rather then 'staging'

<properties>
        <altDeploymentRepository>local-nexus::default::http://nexus/content/repositories/snapshots/</altDeploymentRepository>
        <altReleaseDeploymentRepository>local-nexus::default::http://nexus/content/repositories/staging/</altReleaseDeploymentRepository>
        <altSnapshotDeploymentRepository>local-nexus::default::http://nexus/content/repositories/snapshots/</altSnapshotDeploymentRepository>
      </properties>

should be

<properties>
        <altDeploymentRepository>local-nexus::default::http://nexus/content/repositories/staging/</altDeploymentRepository>
        <altReleaseDeploymentRepository>local-nexus::default::http://nexus/content/repositories/staging/</altReleaseDeploymentRepository>
        <altSnapshotDeploymentRepository>local-nexus::default::http://nexus/content/repositories/snapshots/</altSnapshotDeploymentRepository>
      </properties>

@rawlingsj, this change KurtStam@c7317e9
messes with the information that is in /sonatype-work directory, and the conf/nexus.xml that was overlaid is lost. It then snaps to some default repository config. Not having the staging repository in nexus is a problem when you want to deploy to it!
