The MQTT service declaration cannot have the onComplete method

[TharmiganK]

Description:

$Subject

Even though this is support in the service object definition, the compiler plugin is throwing an error when it is used in the service declaration

Steps to reproduce:

Try to compile the following code:

service /api on new mqtt:Listener(mqtt:DEFAULT_URL, "", "") {

    remote function onMessage(mqtt:Message message, mqtt:Caller caller) returns error? {

    }

    remote function onError(mqtt:Error err) returns error? {

    }

    remote function onComplete(mqtt:DeliveryToken token) returns error? {
        // handle the delivery token
    }
}
