Cannot set PermissionService

Plugins Plugin Development
1

I want to register my own PermissionService to Sponge, but when i try to add it to the ServiceManager it says there is already one. Am i doing something wrong?

This is the method that adds the service:

    @Override
    public void init() throws ProviderExistsException {
        logger.info("Current GameState: " + game.getState());
        logger.info("Current Permission Service: " + game.getServiceManager().provide(PermissionService.class).orElse(null));
        game.getServiceManager().setProvider(Plugin.getInstance(), PermissionService.class, this);
    }

And that’s the resulting log:

[01:41:28] [Server thread/INFO] [CNPlugin]: Adding module: de.craftednature.sponge.cnplugin.permission.PermissionHandler
[01:41:28] [Server thread/INFO] [CNPlugin]: Current GameState: INITIALIZATION

What phase are you setting the PermissionService at?

Sponge adds the default permission service at the INTIALIZATION phase, you’ll need to register at PRE_INITIALIZATION if you want to register your own permissions.

Hmm, you seem to be right. That means a lot of reorganizing work for me though xD

I thought, since ServiceManagers Documentation say’s “Services should only be registered during initialization. If services are registered later, then they may not be utilized.”, that it should work during normal INTIALIZATION…

Thank you. :slight_smile:

Well you could do

@Listener(order = Order.PRE)
public void onInit(GameInitializationEvent event) {
}

Which may do it before sponge, I don’t know for certain

I had the same thought, but sponge is still faster ^^

Ok, now there is another Exception. This one i really don’t understand: http://pastebin.com/raw/fZYzPLai

SpongeBuild: 1.8-1577-2.1-DEV-922

Edit: Ok, maybe i am missing something in my Service … hold on…
Edit2: Fixed it. Thanks again. I really need sleep now! :smiley:
