Forge universal jar file not opening.. check console.. help!

I've been trying to install mods forever and I can see them in my creative inventory but can't place modded entities or anything modded of that matter in the game. Also, when I double click on the forge universal jar file I have (after installing the forge server and following through with the installer) it just says 'check the console for error messages.' The "mods" sections come up when I open Minecraft, and I have mods in my regular Minecraft folder (not connected to my server) in which I want. I don't think these are connecting which is the problem. And, when I put the mods in the forge mods folder there is no point because the forge server jar file won't even open... it comes up with that error. I have been searching for hours on how to resolve these issues, anything will be greatly appreciated! thanks.

I'm not too sure how to check the console. When I open it it just lists a bunch of messages, and even when I search "forge" nothing will come up. I am on a Mac, any ideas?

this is under the forge logs, the correct one? It's labeled "latest.log" under my forge folder.

It's okay, did I post the right one? I don't know what fml is... I don't have any file name like that under where I installed forge. Unless I'm being an extreme noob.

  • Author

okay. So, I downloaded the forge installer, installed the server section of it, double clicked and followed through with that, made sure there was a mod section when I opened Minecraft and now I'm not running it? I'm confused why it didn't create that file. Do you need me to show you anything? 

  • Author

When I start up the server, I click on the Minecraft server jar file I installed. When you enter a new configuration, like 1.12.2 or whatever, it says download server or something along those lines... I have that file and I'm able to get onto the server. I'm not going through an external source or anything, it's just through Minecraft and I'm able to get onto the server. "minecraft_server.1.12.2.jar"

Dude, I know!! I said it in the beginning, the universal jar won't even open. It just says check console for error messages, or something along those lines. I don't know how to use console on mac and can't figure out the problem. 

  • Author

I looked up how to search in console and all examples were different from my computer, when I search forge nothing comes up. Don't be responding trying to help with just a sentence when clearly that won't fix the problem even a little. I'm done with this discussion. Thanks.

Took me all of 10 seconds to do on my phone

there’s 0 reason to be rude to someone helping you on a forum, unless they are clearly being rude, in this case your question is grouped as commonly asked, OS specific and there’s no way one person can know the answer unless they already know everything about your setup

Haye StevenMerlino,
don't listen to this toxigated guys,
I am here to help and tell you that you have to Update your Java Version
(easily by downloading it again from to original Website, just by searching "java download")
then pressing the hidden intalling button, not removing, after opening the Java Download

1.12 is no longer supported on this forum.

Please update to a modern version of Minecraft to receive support.

This is my Forum Signature, I am currently attempting to transform it into a small guide for fixing easier issues using spoiler blocks to keep things tidy.

 

As the most common issue I feel I should put this outside the main bulk:

The only official source for Forge is https://files.minecraftforge.net, and the only site I trust for getting mods is CurseForge.

If you use any site other than these, please take a look at the StopModReposts project and install their browser extension, I would also advise running a virus scan.

 

For players asking for assistance with Forge please expand the spoiler below and read the appropriate section(s) in its/their entirety.

Spoiler

Logs (Most issues require logs to diagnose):

Spoiler

Please post logs using one of the following sites (Thank you Lumber Wizard for the list):

https://gist.github.com/: 100MB Requires member (Free)

https://pastebin.com/: 512KB as guest, 10MB as Pro ($$$)

https://hastebin.com/: 400KB

Do NOT use sites like Mediafire, Dropbox, OneDrive, Google Drive, or a site that has a countdown before offering downloads.

 

What to provide:

...for Crashes and Runtime issues:

Minecraft 1.14.4 and newer:

Post debug.log

Older versions:

Please update...

 

...for Installer Issues:

Post your installer log, found in the same place you ran the installer

This log will be called either installer.log or named the same as the installer but with .log on the end

Note for Windows users:

Windows hides file extensions by default so the installer may appear without the .jar extension then when the .log is added the log will appear with the .jar extension

 

Where to get it:

Mojang Launcher: When using the Mojang launcher debug.log is found in .minecraft\logs.

 

Curse/Overwolf: If you are using the Curse Launcher, their configurations break Forge's log settings, fortunately there is an easier workaround than I originally thought, this works even with Curse's installation of the Minecraft launcher as long as it is not launched THROUGH Twitch:

Spoiler
  1. Make sure you have the correct version of Forge installed (some packs are heavily dependent on one specific build of Forge)
  2. Make a launcher profile targeting this version of Forge.
  3. Set the launcher profile's GameDir property to the pack's instance folder (not the instances folder, the folder that has the pack's name on it).
  4. Now launch the pack through that profile and follow the "Mojang Launcher" instructions above.

Video:

Spoiler

 

 

 

or alternately, 

 

Fallback ("No logs are generated"):

If you don't see logs generated in the usual place, provide the launcher_log.txt from .minecraft

 

Server Not Starting:

Spoiler

If your server does not start or a command window appears and immediately goes away, run the jar manually and provide the output.

 

Reporting Illegal/Inappropriate Adfocus Ads:

Spoiler

Get a screenshot of the URL bar or copy/paste the whole URL into a thread on the General Discussion board with a description of the Ad.

Lex will need the Ad ID contained in that URL to report it to Adfocus' support team.

 

Posting your mod as a GitHub Repo:

Spoiler

When you have an issue with your mod the most helpful thing you can do when asking for help is to provide your code to those helping you. The most convenient way to do this is via GitHub or another source control hub.

When setting up a GitHub Repo it might seem easy to just upload everything, however this method has the potential for mistakes that could lead to trouble later on, it is recommended to use a Git client or to get comfortable with the Git command line. The following instructions will use the Git Command Line and as such they assume you already have it installed and that you have created a repository.

 

  1. Open a command prompt (CMD, Powershell, Terminal, etc).
  2. Navigate to the folder you extracted Forge’s MDK to (the one that had all the licenses in).
  3. Run the following commands:
    1. git init
    2. git remote add origin [Your Repository's URL]
      • In the case of GitHub it should look like: https://GitHub.com/[Your Username]/[Repo Name].git
    3. git fetch
    4. git checkout --track origin/master
    5. git stage *
    6. git commit -m "[Your commit message]"
    7. git push
  4. Navigate to GitHub and you should now see most of the files.
    • note that it is intentional that some are not synced with GitHub and this is done with the (hidden) .gitignore file that Forge’s MDK has provided (hence the strictness on which folder git init is run from)
  5. Now you can share your GitHub link with those who you are asking for help.

[Workaround line, please ignore]
