Solved NullPointerExceptoin...

So, I was doing some class reconfiguration on my laptop.
Getting myself set up to redo, and optimize most of my code.
Anyways...​

I compile everything, and upload it to my server to test it out and make sure everything runs the same...
But I get this.​

Code:

[Server thread/ERROR]: Could not load 'plugins\CameraMode.jar' in folder 'plugins'

I have no idea what could be causing this.
The only things I changed, was that I split up my main class into three different classes, because it was so large. As well as altering how the updater type is determined.

The stackTrace suggests that the problem is coming from my main class.
So here it is.
Let me know if you spot anything out of place that I'm overlooking. ​

This tells you that line 41 in CameraMode.java is at fault.

Code:Java

Entity putMobs = mobs.put(playerr.getUniqueId().toString(), (Entity) playerr.getNearbyEntities(15, 15, 15));

You are trying to run code outside of a method first off, which is bad.
Second, at this point in the code, playerr has never been initialized, just declared. This is probably why you are getting the error.
