Development Assistance VanishNoPacket

I am trying to use VanishNoPacket in my plugin to check if the player is Vanished. This is optional therefore I check if the plugin is not null

Code:

if(Bukkit.getServer().getPluginManager().getPlugin("VanishNoPacket") !=null) {

The issue is though no matter what I do it gives me the following error.

Error (open) Error (close)

Error on Hastebin and not in spoiler.

Basically i've read this as the class is not loaded (because I removed VanishNoPacket) and therefore it doesn't want to load. Why is this the method isn't even being called when it is being enabled.

My Code:
(References you may want to know:
Line 45 = onEnable
Line 462 = isNoPacketVanished Method Being Called At 262)

Umm, why are there static fields in a class that will never ever be instanciated over once?
EDIT: you can get booleans from config instead of parsing string to boolean (FileConfiguration#getBoolean(String paramPath)

Anyway the problem apears to be Caused by: java.lang.ClassNotFoundException: org.kitteh.vanish.staticaccess.Vani
shNotLoadedException
that i think means it is not loaded, Can we see your plugin.yml? have you registered dependensies

 

@DaChiimp Are you sure it's on the server?

 

@bwfcwalshy It's not on the server no because it's optional. This means that if they have the plugin then it uses the code.

plugin.yml

Code:

name: StaffList
version: 2.1
main: com.dachiimp.stafflist.StaffList
commands:
    staff:
        description: Generic base command.

 

@DaChiimp Add softdepend: [VanishNoPacket] also please show us your full onEnable

 

@bwfcwalshy That is my full on enable?

EDIT: Thanks for that softdepend. Forgot about that.

@bwfcwalshy Sorry, forgot to reference that. Line 239 and it is calling the method at 462

EDIT: The error is not fixed.

Still giving me that error.

 

@DaChiimp Check if it exists in onEnable, if so print something like "Hooked into VanishNoPacket"

 

@bwfcwalshy Still nothing. Do you think it may be the API that is broke? Have you tried downloading VanishNoPacket and tried to use it in a plugin but purposely not have it on the server so it is optional usage.

 

@DaChiimp You are getting the error because it is running a VanishNoPacket method when it's not on.

 

@bwfcwalshy I'm not. I check if the plugin is not null first.

 

@DaChiimp I know you are but that is what the error says

Print out a message each time it runs a VanishNoPacket method, see how many print.

 

@bwfcwalshy
I did and it was not called on enable. I am starting to think the API is broke because this error is thrown when you use a older version of WG with 1.8 (obviously a WorldGuard error though not VanishNoPacket)
