Solved Disguising a Player as a mob API

Hello, I am trying to use an API for my plugin to disguise a player as a mob. I am using Lib's Disguise to do this. I have looked at the documentation and I have done everything it requires.
Here is my code:

Code:

public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
Player p = (Player) sender;
if (command.getName().equalsIgnoreCase("try")) {
Entity en = (Entity) sender;
DisguiseAPI.disguiseToAll(en, new MobDisguise(DisguiseType.CREEPER));
return true;
}
return true;
}

I have added it to my plugin dependencies in plugin.yml and yes, it is on my server and reference libraries in eclipse.

Here is the error i get in the server log whenever I start the server:

Code:

I have tried different plugins and API's and they all sucked. Lib's disguises is by far the best.
Ive looked everywhere and couldn't find anything to resolve this error. Any help appreciated! Thanks!

EDIT: although if you have used an API before that works with disguising players as mobs, please let me know.

If there is a way to do this with packets and not using an api that would be very helpful too

 

1. Could not load 'plugins/MandatoryAPI.jar' in folder 'plugins'
2. org.bukkit.plugin.InvalidPluginException: java.lang.NoClassDefFoundError: me/libraryaddict/disguise/disguisetypes/Disguise

 

What? What are you trying to say?
I have the class in my imports and in my server.

 

@Petersoj Do you have the plugin on the server?

 

@dlange Yes, read my first post...

 

@Petersoj But is it functioning in itself? Try using /disguise player Test or something ingame, see if it works.

 

@dlange Yes, it all works by it self. But for some reason when I use the api in my plugin I get those errors and the plugin doesn't load.

Got it working.... There was a typo in my plugin.yml
