You have a NoClassDefFound error, meaning a class was not found, the name of the class that wasn't found, and the line of code that called it. Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice. Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked. DO NOT PM ME WITH PROBLEMS. No help will be given.
December 9, 20204 yr Author okay so the main class is missing?? and how to fix the error? Edited December 9, 20204 yr by Luis_ST
December 10, 20204 yr Your java installation is incorrect. You are running this project in the jre inside your jdk. You need to point your IDE to use the jdk instead. Have you ever want the new operator to return a type that you didn't ask for? Well, now you can!
December 10, 20204 yr Java 15 removed the Nashorn engine that is used by Forge. Downgrade to a supported version.
