Solved [1.7.9+] getOnlinePlayers() error

I took a break from bukkit for like 3 months or more and when I come back getOnlinePlayers gives me an error.. and I'm pretty sure I'm just doing it the exact same way I did it last time..
So yeah, was the method edited?..

If anybody knows how to do this, I'd appreciate if you helped me out.
Here is the code that has the error (at-least that's what the log tells me)

Code:java

for(Player p : getServer().getOnlinePlayers()){
      p.sendMessage("12345");
}

I can provide you with an error log if you want, but I don't think you need it, so tell me if you do.

Error log?

 

You should always post the error.

Try Bukkit.getOnlinePlayers()

I'll try.

You're using a Bukkit API jar that contains the new getOnlinePlayers() method which returns a Collection of players instead of an array. But you craftbukkit jar is not up-to-date with the new getOnlinePlayers() method that returns a Collection hence the error of NoSuchMethod.

 

They do the same thing.

@OP Make sure the version of CraftBukkit on your server is the same as the version of Bukkit you're building against. Or just update both to the latest version.

 

Dragonphase It didn't change anything, but thanks anyway.
Also, It's definitely an error with the getOnlinePlayers()

Yeah, This was what I was looking for, I already saw that it returned a collection and I didn't know what to do.
Thanks.

Okay, I updated it and it works.
Thanks to Gater12 Garris0n, and Dragonphase
