Posted December 29, 201311 yr 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.

December 30, 201311 yr Author 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.

December 31, 201311 yr Author OK, did that and looks like I'm missing libraries to run forge?

January 1, 201411 yr Make sure that the minecraft server jar is named: 'minecraft_server.1.7.2.jar' exactly in the same folder as Forge's jar. I do Forge for free, however the servers to run it arn't free, so anything is appreciated. Consider supporting the team on Patreon
January 1, 201411 yr Author 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.

January 2, 201411 yr Same error, the only log file produced is the "latest.log" from the vanilla server.

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!

January 4, 201411 yr 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.

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.
January 6, 201411 yr -.- 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 do Forge for free, however the servers to run it arn't free, so anything is appreciated. Consider supporting the team on Patreon

January 6, 201411 yr 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... I do Forge for free, however the servers to run it arn't free, so anything is appreciated. Consider supporting the team on Patreon
January 6, 201411 yr 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!
