One or more named builder configurations as a comma-separated list as specified in the "configurations" section of angular.json. The builder uses the named configurations to run the given target. For more information, see https://angular.io/guide/workspace-config#alternate-build-configurations. Setting this explicitly overrides the "--prod" flag.
