     This script prepares Nexus repositories data blobs for ONAP

     Following dependencies are required: nodejs, jq, docker, twine, expect
     By default, without any lists or dirs provided, the resources are expected as downloaded
     during download process and default lists will be used to build the Nexus blob in the same
     resources dir

     Examples:
         $(basename $0) --input-directory </path/to/downloaded/files/dir> -ld --output-directory
            </path/to/output/dir> --resource-list-directory </path/to/dir/with/resource/list>
            # Docker images, npms and pypi packages will be loaded from specified directory
            # and the blob is created
         $(basename $0) -d </path/to/docker/images/list> -d </path/to/another/docker/images/list>
         -n </path/to/npm/list> -p </path/to/pip/list>
            # Docker images, npms and pypi packages will be pushed to Nexus based and provided data
            # lists (multiple lists can be provided)
