Ok some background information first.

 

I am using minecraftforge-universal-4.1.1.251.zip, the more recent version fails to start the server at all.

 

I have installed the forge client into the minecraft_server.jar as instructed and this is the set of errors that I get on the server console as it tries to load.

The minecraft_server.jar runs fine before the forge files are placed inside it, once they have been added in the above errors occur.  I have tried using Open JDK 6 and 7 both produce the same errors in attempting to get the server to run. 

 

(I have had NO issues in appliying forge to the regular minecraft.jar, it runs perfectly fine.)

 

Any suggestions here? Or at least point me in the direction of a solution if it's already been found, as I've looked and have been unable to find anything yet.

Hmm, I suppose I can try that, though this will be the third or fourth time I've re-downloaded it.

 

(Ok just got the most recent build off of Jenkins.  3.2.5.317.  Used a fresh minecraft_server.jar and this is what the terminal spits out.)

Could not find the main class: net.minecraft.server.MinecraftServer. Program will exit.

Nope, just extracted the forge .zip, and dropped all the files into the .jar per the installation instructions.  That's also the error I get if I use the most current versions of Forge.  If i went and tried to find any of the 4.1.1 releases they give me the other wall of text.

The issue is that you are failing at install ALL the files that forge ships, this isn't a forge issue, you just need to be better at copy/pasting files -.-

There is no help we can give you beyond, do it properly.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.
