There isn't supposed to be a jar in 1.12 Did you install Forge while the launcher was running? Have you restarted the launcher since then?

Please provide debug.log

and the entry in the versions folder has a json in it?

Screenshot?

Intellij lets you reattach the project by giving you an option when you right click the build.gradle

Please show the bottom of the version list

Please read the Logs section of my signature below and provide the appropriate log in the appropriate manner.

That appears to be latest.log from your server, that is not what I asked for and doesn’t appear to contain any messages about a client attempting to connect.

What launcher are you using? Please provide a screenshot.

Forge for 1.12.2 and earlier requires Java 8, not earlier, no later

Please read the Logs section of my signature below and provide the appropriate log in the appropriate manner.

Please provide debug.log from both server and client

If you're using Twitch I have instructions on how to get a debug.log from that in my signature below.

We don't provide support for Bukkit here, this is the Forge forum

You'll have to be more specific. Do you mean with a mod? By "world" do you mean dimension?

Can you please provide debug.log files from both server and client from the same login attempt? (I'd like to try to match the timestamps)

Please provide your installer log, it will have the same name as the installer but with .log on the end: Installer: forge-{version}-installer.jar Log: forge-{version}-installer.jar.log Note: If you have Windows Explorer set to hide file extensions(as is the default setting), they will look like this: Installer: forge-{version}-installer Log: forge-{version}-installer.jar

I recognize that icon, and I hate when people say they downloaded it from the "Official Site" instead of giving a URL. You downloaded an installer from a sketchy site and it probably prompted you to install a bunch of crap before getting to this point. Delete everything it asked you to install, delete the file you downloaded, run a virus scan, and get Forge from the proper place.

Please provide debug.log from both client and server using one of the sites listed in my signature below

Spot the difference

Please provide debug.log

That's not the log I asked for
