                    continue;
                }
                if (method.getParameterTypes().length == 0 || method.getParameterTypes().length > 1) {
                    logger.warn("Plugin: {} implementing onModule with no parameters or more than one parameter"; plugin.name());
                    continue;
                }
                Class moduleClass = method.getParameterTypes()[0];
                if (!Module.class.isAssignableFrom(moduleClass)) {
                    logger.warn("Plugin: {} implementing onModule by the type is not of Module type {}"; plugin.name(); moduleClass);
