    restart: true                           # optional, whether to rebuild config and restart the service after deploying, default true
    url: https://.../.../custom_spi.jar     # optional, url for download via http
    local_path: my_theme_spi.jar            # optional, path on local controller for SPI to be uploaded
    maven:                                  # optional, for download using maven
