Plugin API NullPointerException

Now I may just be derping here but I cannot seem to figure this one out. This is the error that I am getting: http://pastebin.com/ezkiH8ey

In my class containing the onEnable method I set up the constustor like so:

Code:java

WorldmotdAPI worldMOTD = new WorldmotdAPI(this);

Code for the class WorldmotdAPI (Note: If you guys see anything that can be improved please to comment on it and criticize it. Thanks )

Code:java

If you need any more info just ask. Thanks in advance for the help!

 

looks like configMotd is null, check that it was set.

 

Yes I knew that. I should have included an example of what is in the config. It looks something like this:

Code:

build:
  motd:
    - 'Welcome to this awesome world!'
  clear-chat: false
  on-player-login:
    enable: true
    motd:
      - 'This message will be sent when the player logs in to build!!'
    clear-chat: false
