getNearbyEntities

Could someone help-me please? I Got that problem with the NearbyEntities and i really dont know how to solve it

public boolean near(Location l) {
for (Entity entity : l.getWorld().getNearbyEntities(l, 9, 5, 9)){
if (entity instanceof Player)
return true;
}
return false;
}

The error appears on "getNearbyEntities" and shows :
The method getNearbyEntities(Location, int, int, int) is undefined for the type World

If you wanna see all the code, here we go : https://pastebin.com/51TqU6zP

 

@timtower
Hello sr, thanks by the answer, i changed it to :

public boolean near(Location l) {
double a = 9;
double b = 5;
double c = 9;
for (Entity entity : l.getWorld().getNearbyEntities(l, a, b, c)){
if (entity instanceof Player)
return true;
}
return false;
}

but it stills not working, appears the same error :

• The method getNearbyEntities(Location, double, double, double) is undefined for the type World

Hello mr @timtower, sorry to take too many time to reply it again, so ...
I am using "spigot-1.8.8-R0.1-SNAPSHOT-latest"

 

@timtower World#getNearbyEntities(Location, double, double, double) seems to have been added in version 1.8.3.

@Oliveirah Are you sure that you're building & running 1.8.8?
