How do i solve?

 

We can't solve your problem at all without any code, but obviuosly there's a ArrayIndexOutOfBoundsException, so you are trying to access an Array element, that does not exist.
Since it is in the command execution part i'd suggest that you used a command without any further arguments, but in your code tried to access the first argument.

 

My guess is he tried gettings args[0] in the onCommand without checking if args.length >= 1.

 

That's what i meant ^^

 

Yeah, except you're right. We do need code to do this, as we can't fix what we can't see. Every tried stitching a piece of clothing in the dark? "OW!" every 5 seconds.

 

There is a very simple (depending on your definition of simple) solution to this, need to see some code first
