Solutions

Method 1: importing package

Relative short code, but version depended and repetive code.

import v1_8;

//...

int ping = ((CraftPlayer) player).getHandle().ping;

Method 2: using Reflection

Version independed, but relative giant and repetive code.

try {
    String bukkitversion = Bukkit.getServer()
        .getClass()
        .getPackage()
        .getName()
        .substring(23);
    Class<?> craftPlayer = Class.forName("org.bukkit.craftbukkit."
        + bukkitversion + ".entity.CraftPlayer");
    Object handle = craftPlayer.getMethod("getHandle")
        .invoke(player);
    Integer ping = (Integer) handle.getClass()
        .getDeclaredField("ping")
        .get(handle);
    
    return ping.intValue();
} catch (ClassNotFoundException | IllegalAccessException
        | IllegalArgumentException | InvocationTargetException
        | NoSuchMethodException | SecurityException
        | NoSuchFieldException e) {
    return -1;
}

Method 3: using interface and importing respectively to implementation

Repetitive code.

Method 4: using library Inia

Short code and version independed.

import inia.ent.PlayerWrapper;

PlayerWrapper wPlayer = new PlayerWrapper(player);
int ping = wPlayer.getPing();
