NoSuchMethodException

Hello. I'm trying to develop a small plugin for my server.
For now it just gives the player a item, but it does not work and I really can't figure out the problem.

Maybe because your class isn't defined as "public" ? :}

 

Oh, thank you, I totally forgot it!
I don't write a line of code from months XD

 

Good spot
