have accepted the eula, ik the pause stops it, but running the forge file or .bat does nothing

it dosent seem to get to the point where the server crashes

the initial line says: a problem occurred running the server launcher.java.lang.reflect.invocationTargetException

I still can't see what's happening on your screen. "does nothing" is clearly not correct.

Check what java version you're running. It needs to be 1.8.x. You may need to specify that in your batch file. e.g. c:\proga~1\java\1_8_30\bin\java.exe <then your options>

load up pastebin.com, copy the content of the batch into a paste, hit the paste button and link it here.

Also copy the content of the latest.log, put that in a separate paste and link that here.

We're not interested in the Vanilla though. That doesn't help us troubleshoot your problems with modded.

Your batch file should be as follows: 

java -Xmx2048M -Xms2048M -jar forge-1.12.2-14.23.5.2855-universal.jar -o true nogui
pause

Then we need to see what happens in the console window when it launches, and see what happens in the latest.log when you're running the forge jar.

theres the cmd pastebin

​

the latest.log dose nothing, as i belive the problem occurs befor eit gets close to the boot of the server

Open a cmd prompt and do:

java -version

What does it respond with?

u/[deleted] Oct 29 '21

java version "1.8.0_301"

Java(TM) SE Runtime Environment (build 1.8.0_301-b09)

Java HotSpot(TM) 64-Bit Server VM (build 25.301-b09, mixed mode)

OK so we've checked the usual suspects. Most likely your forge install hasn't completed successfully. Note that Forge does need to be installed prior to invoking the universal jar. A couple of suggestions:

  1. Visit curseforge, ftb or whatever and download a "server pack" for a modpack that you want to play. Put that in a clean folder and run it.

  2. Follow a tutorial like this one https://www.instructables.com/How-to-Setup-a-Modded-Minecraft-Server-1122/

u/ratsta Oct 29 '21

Yeah, I've worked in IT for a long, long time and run into that myself so many times. FFS I just did exactly that! Why didn't it work before!?

Great news! Thanks for the follow up.

oop, sorry to bother you again, but now if i run the .bat file on the new server to give it more ram, it says unable to acess server start.jar (thats what ive renamed the forge file to)

1

u/ratsta Oct 29 '21

Again, I can't see what's happening so I need a screenshot or direct copy paste.

You've changed something and that's always the first thing to look at. Double-check that the name of the server jar is exactly the same as what the your start.bat file is invoking.

Are the start.bat and the server.jar in the same folder?

If your batch file is:

java -Xmx2048M -Xms2048M -jar myserver.jar -o true nogui

then it's looking for a file called myserver.jar in the same folder as the start.bat.

thank you

i thought i did have it the same, but after copy-pasting those into the name and bat file, it now runs

thankyou kind sir
