Accessing resource bundles in super class

[MagnusMG]

Here is my situation:

• I have an abstract class GeneralCommand and a subclass SpecificCommand.
• In the command annotation of SpecificCommand I specify a resource bundle:
  @Command(name = "spccmd", resourceBundle = "MyBundle")
• In GeneralCommand I have a subcommand make, where I want to use a value from the resource bundle in the description text: @Parameters(description = ["Restrict processing to \${bundle:unitNamePlural:-units} that match this string."]) pattern: String?

The output of spccmd make -h always shows the default value 'units' and never the value in the resource bundle.

Some more facts:

• When I programmatically access the resource bundle with CommandLine.resourceBundle.getString("unitNamePlural") it works fine. So the resource bundle is found and the key is there. (I do this in a Companion object of GeneralCommand; I write in kotlin.)
• When I use an environment variable instead (\${env:unitNamePlural:-units}) it works fine.
• When I skip the whole superclass/subclass thing and implement it all in the same class, it works fine.

I realise that trying to access the subclass's resource bundle from the superclass is perhaps expecting too much, but is there another way of doing this? Can I declare an 'abstract annotation member' in the superclass that the subclass has to implement, in order to insert a value specified in the subclass in the superclass's annotation?

I envisioned that resource bundles would be declared on the top-level command when I designed this feature.
That way, all subcommands would not need to declare a resource bundle of their own, they can share a single resource bundle.
(19.3. Shared Resource Bundles)

(Subcommands may still have their own resource bundle to override values in the shared bundle of the top-level command, if necessary, but this would be an exception and usually not needed.)

Can you follow this pattern?

Yes! When I added the command annotation to the superclass and put the resourceBundle attribute there as well, it all worked. Awesome!

Great to hear that!
