how do i fix?
Try using a Java version lower than 16
Forge isn't currently compatible with Java 16 due to a change in reflection restrictions.
Forge for 1.17 should be compatible with Java 16 when it comes out, as that is the Java version Mojang will be shipping with the game then.
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 ($$$)
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:
...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:
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.
