Plugins Plugin Development

thanks :slight_smile: I had gotten that config setup from Simple plugin configuration tutorial? - #3 by intronate67

Now I’m getting an error about not being able to inject something though :S

  1. Error injecting constructor, java.lang.NullPointerException

    while locating com.patey07.NTCCore.NTCCore
