Event not fired

I'm developing a plugin in 1.12(because it's for a friend, and his server is still in 1.12 lol), but can't get my event to fire... Code:

Code:

public class OnItemInHopper implements Listener {
   
    @EventHandler
    public static void onItemInHopper(InventoryMoveItemEvent event) {

and:

Code:

public class Core extends JavaPlugin{
   
    @Override
    public void onEnable() {
       
        this.getServer().getPluginManager().registerEvents(new OnItemInHopper(), this);
       
    }

I get no errors in the console, so that's weird...
Anyone that knows a solution?

 

@TFOXTom Have you tried printing a simple message to the console in the event? (outside of any if statements)
EDIT: Try removing the 'static' keyword from the event.

 

@KarimAKL sorry for the late reply.
I have tried that. Removing static doesn't work...

 

@TFOXTom Any errors in the console? Did you get the message when trying to print it to console outside of any if statements in the event?

 

No errors, didn't get the message...

 

@TFOXTom Are you sure it's the correct event?

 

I'm 95% sure. Im trying to check if a item is moved to or from a hopper, so it's the good one right?

EDIT: found the problem. There probably is a bug in my bukkit.jar, where the event is only fired when the interaction is between two TileEntities, and not via a player...

 

The InventoryItemMoveEvent can't be caused by a player. It is called exclusively when a hopper moves an item to or from a container, which has no relation to a player. Listen into the InventoryPickupItemEvent instead. There is no player association with that, either, though.
