Im trying to make a 1.12.2 server and i started it up with the minecraft_server_1.12.2 thing and then i agreed to the eula and ran it again, but i can't run forge and only the vanilla server. I tried using a batch file to start the server and i get this error:

here's a screenshot of my folder (i renamed some files for convenience) i have 2 batch files because i saw something that said to remove the nogui line from it

 

 

I'm quite certain that you are using a more recent version of java that is not supported by older forge. For 1.12.2 forge, I use oracle's java version "1.8.0_333" (java 8).

https://www.oracle.com/java/technologies/downloads/#java8-windows

The installation process is not very easy, so I would recommend following a tutorial (for example).

 

Best of luck.

a modlist here too

I'm actually using java 8, i'll try reinstalling it

@echo off

Here's my start.bat if you want to take a look. I grab the java from "C:\Program Files\Java\jre1.8.0_331\bin\" -> which is my JAVA_HOME environmental variable.

Then I run the jar file "forge-1.12.2-14.23.5.2860.jar"

Could you show your output on "java -version" and "echo %JAVA_HOME%" ?

I tried your start.bat and I made sure java 8 was in the spot it was in, but it just wouldn't open at all

What do mean by  "java -version" and "echo %JAVA_HOME%" 

I don't really know where to find that

I fixed your start.bat file, it was just a file naming issue but it still gives me the same error
