Class Not Found Exception: io.advantageous.reakt.promise.PromiseHandle

[m4mark]

Going through the totdo-Statd tutorial the 'TodoServiceMain' class spat out the not found error, it appears to centre around this statement :

final ServiceManagementBundle serviceManagementBundle = serviceManagementBundleBuilder().setServiceName("TodoServiceImpl") .setManagedServiceBuilder(managedServiceBuilder).build();

Admittedly Java is not my first language so not certain if I failed to do something.

Also, I had to replace some code in the 'TodoServiceImpl' class in order to get it to compile, see below for an example, was this the right thing to do?

@Override
@POST(value = "/todo")
public Promise<Boolean> addTodo(final Todo todo) {
    return invokablePromise(promise -> {
        /** Send KPI addTodo called every time the addTodo method gets called. */
        mgmt.increment("addTodo.called");
        todoMap.put(todo.getId(), todo);
        //promise.accept(true); // **This line was removed**
        promise.resolve(true); // **and replaced by this one**
    });
}

Any help would be most appreciated.
