Forge 10.12.0.976 for Server will not run

cyberjudge · December 29, 2013

Hello All,

I'm running my own Minecraft server. I installed forge-1.7.2-10.12.0.976 using the jar installer however when I now click on forge-1.7.2-10.12.0.976-universal.jar it does not open. Did I do something wrong?

I guess I should say the server I'm running on is a computer I have here at my home. It's running Windows 7 64 bit. Not sure what else I can say to help get an answer. Just let me know if you have further questions.

Logs?

cyberjudge · December 30, 2013

Log is empty. I cleared the log and tried running the jar file and the log file remained blank. Now I'm running the file in the path C:\minecraft server\1.7.2. The log I looked at was latest.log in the logs folder. and I don't see a forge log file unless it is not stored in the C:\minecraft server folder.

luacs1998 · December 31, 2013

Run your forge jar from the command line.

cyberjudge · December 31, 2013

OK, did that and looks like I'm missing libraries to run forge?

Make sure that the minecraft server jar is named: 'minecraft_server.1.7.2.jar' exactly in the same folder as Forge's jar.

cyberjudge · January 1, 2014

Yes it is. I even tried renaming my 1.7.2 folder, recreatign it, redownloading 1.7.2 jar from https://s3.amazonaws.com/Minecraft.Download/versions/1.7.2/minecraft_server.1.7.2.jar and then downloading the newest release of forge and copying that jar to the 1.7.2 folder. The minecraft_server.1.7.2.jar runs no problem and I can log in to it from my client side computer. However Forge is still not launching.

Same error, the only log file produced is the "latest.log" from the vanilla server. I can't get IE or Chrome to upload it here for some reason so I'll paste its' contents at the bottom.

I have a hunch you don't care what's in the sub folders under world but let me know if you do.

I've tried 9.76, 9.81 and 9.82: same error. I've used the jar installer and the Win installer. I've been pointing the installers at empty folders and letting the installer download the server jar as well as the forge jar. My server is Windows 2012 SP1 running Java 7 r45 w/ 32 and 64 bit variants installed. I run the minecraft server once before running forge. The server runs fine and my client can connect to it. When I run the forge jar using the java command shown above I get the output above. I've been running Forge servers for about a year-ish now. (since about 1.32-ish of MC)

Thanks for your attention!

Apparently, it was broken for the first few builds.

Just run with java -cp minecraft_server.1.7.2.jar -jar {forgejar}

That'll work untill the next build which will have the fixed path.

Getting the same thing with Forge 982.

Noted when I ran the vanilla 1.7.2 server (which spawned fine), I waited for the server to completely generate the world and idle.. I typed "stop" to shut it down cleanly and allow me to run Forge and I was greeted with this shut down "appender" error: (look at the end of the boot log pasted below)

I updated to forge 1.7.2.10.12.0.991 and still not successful launching minecraft server with forge. Error that comes up when I run the bat file I created is:

Press any key to continue . . .

Bat file simple does the following:

@echo off

java -Xms1000M -Xmx1000M -jar forge-1.7.2-10.12.0.991-universal.jar nogui

pause

And I can run the server using the above bat file but pointing to minecraft_server.1.7.2.jar just fine

LexManos · January 4, 2014

Fucking son of a bitch abrar broke it again -.-

Either way the problem is this:

minecraft_server.1.7.2.jar is not in the class path

The solution:

Add minecraft_server.1.7.2.jar to the class path.

If you can't do that you shouldn't be hosting servers.

If you can't figure that out, then just rename 'minecraft_server.1.7.2.jar' to 'minecraft_server.1.7.2' Abrar deleted the '.jar' when he moved my code, it's been fixed but something fubared it again.

I even tried renaming the server jar:

And I can still run the minecraft 1.7.2 server file just fine by itself without Forge. This same issue has been happening for a half dozen tested versions for me from 976 through 993.

I appreciate the product and the hints at solution but I'd don't appreciate the aspersion. I've supplied the classpath in multiple ways (explicitly and by running it from the current folder the jars reside in) and it has not resolved the issue. I also tried renaming the server jar as suggested to remove the ".jar" and that too did not change the outcome.

-.-

How about this

Make sure that you have BOTH minecraft_server.1.7.2 AND minecraft_server.1.7.2.jar in the folder

That way when you use a broken version it'll work

And when you use the fixed versions (993) it'll work.

I'm using 993 above and still have the error. I wonder if I'm experiencing what you're suspecting.

(with and without .jar on server file)

Humm, somehow jopt dissapeared from the server jar.. Use 994 it has it fixed, and i've tested fully.

Got to love one broken thing hiding another...

Confirmed: 994 runs fine and 1.7.2 clients w/ 994 Forge connect fine.

Thank you for following through on this!
