InjectableComponent on methods not working properly

[maurxce]

@Configuration
public class DependencyProvider {

    @InjectableComponent
    public PlaceholderHook createPlaceholderHook() {
        //return isEnabled("PlaceholderAPI") ? new PlaceholderHook() : null;
        return new PlaceholderHook();
    }

    private boolean isEnabled(String plugin) {
        return Bukkit.getPluginManager().isPluginEnabled(plugin);
    }
}

This does not happen when I annotate the PlaceholderHook class directly, but I can't do that since PlaceholderAPI is a softdepend

If I annotate the PlaceholderHook class directly, I get the error mentioned in https://github.com/FairyProject/fairy/issues/168

[maurxce]

This was a follow-up issue, seemingly caused by #168 Annotating methods works fine.

[maurxce]

This time the problem happened with an empty constructor.

@Configuration
public class DependencyProvider {

    @InjectableComponent
    public PlaceholderWrapper createPlaceholderWrapper() {
        return new PlaceholderWrapper();
    }
}

It seems as if all my @Configurations just broke overnight

Edit: I didn't notice that I used the same example class as when I created the issue. This also happened with other configurations, but seems to work if classes get annotated directly

@Configuration
public class ItemProvider {

    @InjectableComponent
    public ItemFactory createItemFactory(Processor processor) {
        return new ItemFactory(processor);
    }
}

@Configuration
public class ProcessorProvider {

    @InjectableComponent
    public Processor createProcessor(PlaceholderWrapper placeholderWrapper) {
        return new Processor(placeholderWrapper);
    }
}

Can you send the error here if any? if there is no args constructor in the configuration, it shouldn't throw any error.

[maurxce]

Can you send the error here if any?

It's the same error as shown in the issue description (just for the other classes as well), which is why I reopened this.

The behavior is pretty odd, sometimes the configurations work and other times they don't. I wasn't able to find any pattern myself, so I just stopped using configurations wherever possible at this point

[LeeGodSRC]

It sounds quite odd as I hasn't face the issue in any of my project, can you try to replicate a minimal reproducible project and send it here?

[maurxce]

I can try to do that, it just might take a while since it's pretty inconsistent from what I've seen
