[1.8] get EntityPlayerMP from String

[Userman]

i'm in forge 11.14.1.1334

i'm trying to get the EntityPlayerMP instance of an online player from a string

i tried this way

List list = MinecraftServer.getServer().getConfigurationManager().playerEntityList;
        for (Object aList : list) {
            EntityPlayerMP p = (EntityPlayerMP) aList;
            if (p.getName().equals(stringName)) {
              //code here
            }
        }

 

but it always gives me this error in console

java.lang.NoSuchMethodError: net.minecraft.server.MinecraftServer.getServer()Lnet/minecraft/server/MinecraftServer;

 

any help is appreciated

make sure to only call this on server side

[61352151511]

FMLCommonHandler.instance().getMinecraftServerInstance().getConfigurationManager().getPlayerByUsername("");

 

Should work on both sides.

i'm actually making a plugin so it's only serverside, and i'm not using forge much, i need it only to get some player data out of another mod running on the server, everything else is handled by sponge.(yeah maybe i should use UUIDs instead of Strings - my problem is that everytime i test the code it gives me the "NoSuchMethodError" on getServer() or getConfigurationManager())

 

After seeing how any code i try gives me always the same error most likely my problem is that i didn't setup the project correctly (i'm not really using gradle, i just added forge jar as external dependency and works fine for other tests i did).

 

I'd rather not switch to gradle because for what i need to do it seems pretty time consuming to learn.
