Plugin Not Working! [Please Help]

Ok so I am attempting at my first minigame.
I am really stuck though because when I tested it on my localhost ( :25565 ) server it worked PERFECTLY, but when I try it on an actual server (Hosted by Fluctis, I don't think that has anything to do with the problem though) it doesn't appear in the /pl list.
This is what my console says:

Code:

Could not load 'plugins\/War.jar' in folder 'plugins'

Any help?
By the way this is my plugin.yml:

Code:

main: com.gmail.woodyc40.arenapvp.ArenaPVP
 
 
name: War
 
 
version: 1.0.0
 
 
description: Advanced PvP Minigame
 
 
commands:
 
 
    join:
 
 
      description: joins arena
 
 
      usage: /<command> [id]
 
  create:
 
 
      description: creates arena
 
 
      usage: /<command>
 
 
    remove:
 
 
      description: removes arena
 
 
      usage: /<command> [id]
 
 
    leave:
 
 
      description: leaves arena
 
 
      usage: /<command>

 

Please put traces/code/plugin.yml in code brackets, it is far more readable.
The error is that your compile version doesn't match the one running on yo server, I suppose you compile on 1.8 where server is 1.7 (java version not bukkit version)

 

@mine-care
How do I do this? I mean the compiling?

 

@feff890 just on your IDE change the compiler settings to a lower version of java :- ) plenty of tutorials to look through, that depends purely on your IDE

 

@mine-care
Ok but why does it work on my localhost server if the compiler settings are too high?

 

Because since you are running the server on the same machine that you compiled the code it works. The newer versions of java are not yet standard so different machines will probably be running earlier versions.

 

Ok thanks uksspy and mine-care!
