Plugin has Error: NullPointer Exception

When I try to run the plugin on the server, it fails to load and gives a NullPointer Exception error. It needs to be fixed, I have the plugin here to download. Can anyone help me out and fix it and tell me what's wrong with it?
Plugin: https://dl.dropboxusercontent.com/u/91715928/HerobrinesLabyrinth.jar

 

Post the error log too

 

Here's what the server gives me when I load it https://dl.dropboxusercontent.com/u/91715928/MVM Pictures/NullPointException.png

 

Is that a custom plugin?

 

Yes my brother has been working on it for quite some time.

 

Does he have a plugin.yml?

 

I'm sorry. I have no idea what line 45 means here. Yes, there is a plugin.yml made that he said he set up correctly; obviously not since the plugin is broken now.

Ok NullPointer was fixed. My brother figured out what was wrong. Now it is giving a whole new error. Can someone please just download the plugin from the link above and check it for errors?

Who is the plugin author?

 

My brother. He made it himself as a CUSTOM plugin!

 

Have you talked to him about this? If he made it, he will have the best understanding of how it works

 

Wait can you post the server.log so people can actually see whats wrong.

 

Server log is at my second or third post here. I tell him every answer IO get from here and nothing has helped... However we are getting close. It now says (Is it up to date?) next to the error.

 

Moved to plugin development since this is more or less asking for help with a local plugin.

 

Post the server log and .java file to pastebin then give us links.

Looking at your brother's code, I'm pretty sure only your main class can "extends JavaPlugin". Then for the other classes you can create the class constructor and either register them as a command or listener if necessary.

Code:

public Main pl;
 
public <AnyClass> (Main i) {
    pl = i;
}
