Solved Error - Custom Entity Type

So, I used this tutorial: http://bukkit.org/threads/nms-tutorial-how-to-override-default-minecraft-mobs.216788/ to help me make my own NPC, however it seems to give off errors.

Stack trace:

Code:

and the second error, is in my main class and the error is on this line:

Code:

CustomEntityType.registerEntities();

 

java.lang.ClassNotFoundException: net.minecraft.server.v1_7_R3.EntityZombie

Hmm... looks like you run onb 1.7.9 and it and you import 1.7.3

 

I'm using a 1.7.9 bukkit to import

It's solved, I was using the wrong versions
