    <!--
        This module should have no external dependencies. The following dependency is acceptable ONLY
        due to the fact that it is an optional dependency, and NiFi functions perfectly without it.
        Adding a dependency on nifi-api does not bring in any transitive dependencies.
        The dependency is provided here because Swagger Annotations are used within the Versioned Components
        objects of the NiFi API in order to provide documentation for generating REST API's, generating clients, etc.
        While NiFi does not need these, any application that wants these capabilities can achieve this
        simply by adding their own dependency on Swagger Annotations.
