org.bukkit.command.CommandException: Unhandled exception executing command 'loanmoney' in plugin YouLoan v1.1

 

You have a null point exception, start making console print statements and track her down.

Edit: it appears to be in your onCommand handler, put a console print in between every line of code inside that function, that prints "reached 1", "reached 2" etc, then run the plug-in again and cause the same crash.

In the console you will see:
reached 1
reached 2
reached 3
reached 4
Crash info...

The code that resides after the last successfully reached console print is your problem code (unless it's a function call, then the null might be coming from the function call). This likely isn't the best way to do this, but it works 100% of the time.

 

The error is in line 74 of CommandHandler.java as can be seen here:
at me.jeroende2e.youloan.CommandHandler.onCommand(CommandHandler.java:74)

 

can someone make a new loan plugin?
