Hello, I can't install MCreator on my laptop (ubuntu 16.04 LTS). I have already unzip the file but when I run the java command, I have this text.
java -jar mcreator.jar[Sun Aug 12 09:05:27 CEST 2018] Exception in thread "main" [Sun Aug 12 09:05:28 CEST 2018] java.lang.IllegalArgumentException: object is not an instance of declaring class
