@CheifKeef You need these:

1. https://bukkit.org/threads/new-devs-how-to-make-your-plugin-right-make-it-better.317054/
   
2. http://wiki.bukkit.org/Event_API_Reference

 

You cannot compare an ItemStack to an ItemStack; their object IDs will always differ.
What you need to do is retrieve the player's hand held item and run checks on it.
There are plenty of Bukkit guides that will do so. Here is a list that Google Compiled:
https://www.google.com/webhp?source...or+player+holding+item+bukkit+site:bukkit.org

 

You can using .equals or .isSimilar

 

When you will fix your code there could be another problem and that is spawn-protection. Every server has spawn protection in server-properties.yml and it could block right click on spawn protected area. (If you want to disable it just set spawn-protection to 0)
