Component flow not working

[piotrooo]

For following ComponentFlow:

List<SelectItem> names = List.of(
        SelectItem.of("Name 1", "n1"),
        SelectItem.of("Name 2", "n2"),
        SelectItem.of("Name 3", "n3"),
        SelectItem.of("Name 4", "n4")
);

ComponentFlow componentFlow = componentFlowBuilder.clone().reset()
        .withStringInput("login")
        .name("Login:")
        .defaultValue("j.doe")
        .and()

        .withStringInput("password")
        .name("Password:")
        .maskCharacter('*')
        .and()

        .withNumberInput("id")
        .name("User ID:")
        .required()
        .and()

        .withMultiItemSelector("multiple-names")
        .name("Names:")
        .max(2)
        .selectItems(names)
        .and()

        .withSingleItemSelector("single-name")
        .name("Name:")
        .and()

        .withPathInput("file")
        .name("File path:")
        .and()

        .withConfirmationInput("confirm")
        .name("Confirm:")
        .and()

        .build();

ComponentFlow.ComponentFlowResult flowResult = componentFlow.run();
ComponentContext<?> context = flowResult.getContext();

We are getting errors:

Same as #1233 I guess. This is a regression of d396282. Those resources should be put back but in the jline module not the core module. Any PR is welcome, otherwise I will take care of that for GA.

Yes, it looks similar.
