Issues with MCForge server 3.2.4.114

[ZyloWolf]

Hello all,

 

I've been setting up and using my own servers for a while now and have never really run into any complications yet. I decided the other day to attempt to mod one of my servers and expand my MC gaming experience. So I seeked out 2 nice mods I thought I'd enjoy playing with and was successful in installing them client side. I began to install the same mods into my server so I could play on there but ran into problems with MCForge. While augmenting the bukkit.jar file with MCForge I get an error stating:

I know exactly what file is causing this issue from a little trial and error, it is the file:

 

MinecraftServer.class located in the minecraftforge-server-3.2.4.114.zip, under net, minecraft, server.

 

I do not know exactly why this error is popping up that is puzzling me, it seems to be the only thing thus far in preventing me installing my mods. I've seeked out information through youtube and on other forums only getting mixed responses.

 

I have up to date versions under 1.2.5 of all that is required to mod both my client and my server, it worked okay for the client but I just cannot grasp why it is not working for the server. I have up to date versions of java and installed everything from scratch "Vanilla". I've even tried using older versions of MC and all the mods for that MC version but run into the almost the exact same error. I'm just absolutely puzzled right now, if anyone can tell me whats going on that would be greatly appreciated. thank you in advance.

Dont use the Vinella distro on bukkit.. simple as that. Go get the bukkit port -.-

So there is a version of minecraft forge that is designed for bukkit servers? I did not know that, thank you. I'll do some more research and try a few things out then and see if that clears up the problems I am having. thanks again for the info.

 

OH btw, when I said I used the same mods for the server I actually meant I used the same ones designed for servers. so I had two copies of each mod and MC Forge, one for the client side and one for the servers.

 

~Edit~

 

Got it working now, had to do a bit of research but it was quite simple. thanks again :3
