Gekolib Animations Not Working.

I have been trying to make a boat with custom animations for so long. Nothing has worked. Please don't link to another form topic. I've checked them all. Please if anybody can help with NEW information... I will literally be so grateful. I made my model with gekolib animations on mcreator 2020.5 with the API checked and the plugin installed. I put the animation in an animation folder. I made sure the names matched. I even went into the files and changed the names to match. EVERY GOSH DARN TIME I get the same error. 

The game crashed whilst exception in server tick loop
Error: java.lang.NoClassDefFoundError: software/bernie/geckolib/animation/model/AnimatedEntityModel
Exit Code: -1

Please for the love of god help me.
