 |inverseOperations|Generate an application that will publish messages to `publish` operation of channels and read messages from `subscribe` operation of channels. Literally this flag will simply swap `publish` and `subscribe` operations in the channels. <br> This flag will be useful when you want to generate a code of mock for your main application. Be aware, generation could be incomplete and manual changes will be required e.g. if bindings are defined only for case of main application.| No       | `false`                  |
 |javaPackage|The Java package of the generated classes. Alternatively you can set the specification extension `info.x-java-package`. If both extension and parameter are used, parameter has more priority.| No       | `com.asyncapi`           |
