  - Temporary fix for jenkins

    Temporary fix for the issue where maven running on jenkins
    is not able to find the platform logic installer zip file
    in the maven local repository. By setting this version to
    snapshot, maven will be able to find the version in nexus
    that was build by another job, since it can't find the one
    being build by the docker build job.
