Forge jar Runs, but Doesn't Open Anything/Crashes

Ash White

Recommended Posts


I have been trying to switch a vanilla server over to a forge modded server with the intent of only installing server-side mods. My issue is that when I double click the forge jar I get a loading blue circle for a few seconds and then nothing happens. Below are the stack trace and log for this error, as well as what I have tried and what I know.


I have uninstalled and reinstalled forge-1.14.2-26.0.62 four-six times, every time it would download and set up the necessary files, then I would start the minecraft server jar and it would set up its files, and I agreed to the EULA, then I could not get the forge jar file to run. I have also tried it with running the Minecraft server jar first on a fresh install. When I double-click the Minecraft server jar file it runs and I get the terminal, but when loaded it appears that forge is working but only one mod functions out of three. The forge-based clients can connect as well, and they can play without any problems, but again two mods don't function. At the moment, I am unsure whether forge or the mods are at fault, but when reviewing the logs and stack trace it doesn't seem to have a definitive answer, but I only barely know how to read them. I do know that there haven't been reported issues with the two mods that are failing with their 1.14.2 versions. They also don't appear as loaded and  /"modname" does not do anything.


For reference, I am using Java version 1.8.0_211.


I have googled the visible error marks on the stack trace and tried to find relevant forums and have failed, as most issues were related to something else, such as the Java version being wrong, or the EULA still being marked false. Also, I have tried to start it using a .bat file but that seemed to only make it worse. My current guess is that forge isn't being loaded at all, but I am unsure how to fix this issue.


Thanks, in advance.

First I would suggest updating to 1.14.4

Second you should change the name of one of your folders, exclamation points have special meaning in Java and they mess with file paths

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.


Logs (Most issues require logs to diagnose):


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:

  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.






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:


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:


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:


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.

I would update to 1.14.4 but the mods I am using aren't updated to that version yet. Also, thank you so much it appears the exclamation point was the issue! Very frustrating but I am learning code at the moment so I should have known better, again thanks a lot!!
