getOnlinePlayers() Won't work!

Hi, I want my plugin to broadcast jukebox music to all players. I've been trying to loop on all the players, but it doesn't seem to work, I wrote the code:

Code:java

for(Player players : Bukkit.getOnlinePlayers())
{
players.playSound(players.getLocation(),Sound.GHAST_SCREAM2, 500, 1);
}

but from what I've checked it doesn't enter the for, and I get this error when it happens:
[Server] INFO Caused by: java.lang.NoSuchMethodError: org.bukkit.Bukkit.getOnlinePlayers()Ljava/util/Collection;

 

SpiyCrap Bukkit.getServer().getOnlinePlayers()

I suggest you take a look at this.

thats really strange for me it should work whilst I know that method is changed from Player[] to Collection in the latest version only .length should now be called .size(), are you sure the error is from that plugin?, and you don't have any npc like plugins running at that moment just in case that may modifies the CraftServer's dedicated player list?

already tried it, not difference.

The thing is, I cant even call for getonlineplayers, I tried to move it into a collection, but it seems like it fails to call for it and everything that happens is a crash.

well, by the error it clearly says that "there is no such Method" - [Server] INFO Caused by: java.lang.NoSuchMethodError: org.bukkit.Bukkit.getOnlinePlayers()Ljava/util/Collection;
the only plugin the server is running is mine. also it says:
29.06 16:19:44 [Server] INFO org.bukkit.event.EventException
29.06 16:19:44 [Server] ERROR Could not pass event PlayerMoveEvent to SpookCraft v1.0
29.06 16:19:44 [Server] INFO ... 13 more

(the getonlineplayers is triggered by playermoveevent - I know I shouldn't have done it like that, its just an experiment).

please help, I haven't found anyone with similar error to mine and I really need to use it for my plugin, maybe I'm using the wrong javadoc or bukkit verison? everything else in the plugins works just fine...

Update the server.

 

SpiyCrap Theres nothing wrong with getting all players on player movement but i think it may cause the server to spam that event and maybe prevent lag? im not for sure and try updating your server like Garris0n said. It should help a little bit.
and im not for sure you supposed to use java/util/collections ? Kindof curios. but i have no clue

 

I feel kind of stupid now, that was the fix. The host was running on R2 build

 

mactown21 1. Bukkit.getOnlinePlayers() and Bukkit.getServer().getOnlinePlayers() is basically the same thing.
2. Getting all players on all movement could easily be wrong - the event gets fired a lot and most of the time people use it needlessly, thus wasting resources. Also, not sure what you meant by "prevent lag"
