Plugin won't work

So i already disabling item pickup, but i want it to remove that item when the player tries to drop it (press q).
This is my code:
@EventHandler

public void onPickUpItem(PlayerPickupItemEvent event){

Player player = event.getPlayer();

if(!player.hasPermission("playerAbilities.allowed")){

event.setCancelled(true);

}



}


And i also tried to disable exp pickup but it seem to not work, this is the code:
@EventHandler

public void onExppickup(EntityTargetEvent event){

Entity e = event.getEntity();

if(e instanceof ExperienceOrb){

event.setCancelled(true);

event.setTarget(null);

}

}

 

@BlueCraftMC
Please use the Insert>Code tags around your code. It's easier to see formatting that way.

 

For the removing of "q" to drop just cancel and remove items on ItemDropEvent then for the exp changing use PlayerExpChangeEvent. (Or stop mobs from dropping the exp all together)

 

Make sure youve registered events in your main class and that your plugin.yml is set up correctly. Is the code giving any errors?
