code: def get_version_url(self, full_name, packaging, version, descriptor=None):
          
          group, artifact = _parse_full_name(full_name)
          return self._urls.get_url(group, artifact, packaging, version, descriptor)
docs: Get the URL to a specific version of the given project, optionally using
          a descriptor to get a particular variant of the version (sources, javadocs, etc.).
  
          The name of the artifact should be composed of the group ID and artifact ID
          (if available). E.g. "com.example.project.service". Depending on the repository
          layout, the ``full_name`` might only be the artifact name.
  
          Packaging should be the type of file used for the artifact, e.g. 'war', 'jar', 'pom',
          etc.
  
          The descriptor may be used to select javadoc jars, sources jars, or any other
          assemblies created as part of the version of the artifact.
  
          Example usage:
  
          >>> client = new_maven_client('https://www.example.com/artifactory', 'libs-release')
          >>> client.get_version_url('com.example.users.service', '1.4.5', 'jar', descriptor='sources')
          'https://www.example.com/artifactory/libs-release/com/example/users/service/1.4.5/service-1.4.5-sources.jar'
  
          The example above would return a path object for the sources jar of version 1.4.5
          of some hypothetical user service.
  
          This method does not make any network requests.
