[Help] Set the Real MOTD?

I have this code in my plugin to set the motd to the game state and it works perfectly

Code:java

@EventHandler
public void onPing(ServerListPingEvent e) {
    e.setMotd(getState());
} 

When I ping the server in the server list it displays the motd correct motd to me.

The problem is that I have some code that pings this servers motd in an external server and It displays the motd defined in this servers config file instead of the motd set in the code above. The ServerListPingEvent appers only to get activated by a player pinging the server and not an external servers ping thus not setting the motd.

Is there a way for me to set the motd in the server config file through a plugin?

 

I mean, you could modify it, but it would need to be restart in order for the servers settings to be reloaded.

Are you sure the service your using just doesn't have the MOTD cached?

I have this class im using, with the <IP> <Port> replaced.
Doing
Ping.ping();
Should update it all

Soo, if you wanted to use NMS/Reflection, MinecraftServer.class stores the MOTD as a String, I believe

 

ksbdude

Code:

import org.bukkit.craftbukkit.v1_7_R3.CraftServer;
import net.minecraft.server.v1_7_R3.DedicatedServer;
 
 
DedicatedServer s = (((CraftServer)Bukkit.getServer()).getHandle().getServer());
String MOTD = s.getMotd();
s.setMotd("WhatEverYouWant");

ksbdude im not really experience with writing reflection but here is what i could do to set it with reflection. if anyone knows how i would fix this reflection tell me. also you would need a way to get the nms class.

it would go something like this. dont use this

Code:

public void setMOTD(String newmotd) throws NoSuchFieldException, SecurityException, IllegalArgumentException, IllegalAccessException{
    Class<?> nms = net.minecraft.server.v1_7_R3.DedicatedServer.class;
    Field f = nms.getDeclaredField("motd");
    f.setAccessible(true);
    String obj = "old motd";
    f.set(obj, newmotd);
}
}

Pretty good. Just note that to set a variable using field, the arguments are f.set(theObjectThatIsBeingAffected, theValue)

In this case, you would need to get the DedicatedServer instance, and do f.set(instance, "motd here);
