Forge server using wrong java version

Hi, I have a problem with my server... I have java jdk 13 installed because I need it for netbeans. And I also have java jre 8 and jdk 8 installed too. 

The problem is that the java path is already set to jre 8, and when i use java -version on cmd, it says that I am using java 8, but when I try to open my forge server ( 1.14.4 ) it doesn't load, and in the logfile I can see that it is trying to launch with java jdk 13.

The normal minecraft server launcher starts perfectly, and my minecraft client ( with forge and mods installed ) starts without problems too (which indicates that the java version is set properly to java 8 )... I know that forge only use java 8 or java 10, but if my java version is  set to java 8, why is the forge server launcher the only one that is trying to launch with jdk 13?

 

When I uninstall jdk 13 the forge server starts perfectly, but when I install it again it doesn't. I've been searching for answer for almost three or four hours before making a post... so please, lend me a hand ??

 

Here is the latest log:

Instead of invoking "java", use the full path to the Java 8 java.exe

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.

Hey thanks for replying, but I did not understand you... what do you mean with "invoking"? When i'm going to start the server I just double click the "forge-1.14.4-28.1.90.jar" and nothing happens, it only creates the log file. Could you be a bit more explicative? I don't know if there is a way to start it with a .bat file if thats what you say.

Thank you so much!! I'll leave here what I did to get it working just for helping other users that have the same issues:

 

- I opened a cmd console in the server folder ( shift + right click, and then open powershell ).

- I wrote "java -jar forge.jar" and then it started with java 1.8.

 

When I put the full path to the java executable it says "C:\Program is not a valid command", so I tried to use just  "java" and it worked. Thank you again for the help!!

You can run a jar file from the command line using java -jar jar file here. If you use the full path to the java executable instead of just java you can specify which Java to use.

Full path? I have been having this issue and as the other person stated, it simply says it is not a valid command. 

Do you have an example of the code required?

It's very weird. This is how I did it, running this from the server folder

"C:\Program Files\Java\jre1.8.0_301\bin\java.exe" -Xmx8096M -Xms2096M -jar forge-1.12.2-14.23.5.2854.jar

I'm having a similar problem but that method doesn't seem to work for me. I think the quotes might be messing it up but I am unsure on that. If I remove the quotes it can't detect the space between program and files at the beginning as one filename, so it assumes you are trying to run a command called C:\Program, which doesn't exist, and not trying to follow a set file path. I am trying to find a way to bypass this by using file shortcuts but it isn't working. It keeps saying that they cannot find that file path.

I used this
"C:\Program Files\Java\jre1.8.0_333\bin\jave.exe" -Xmx16G -Xms8G -jar "Blightfall.jar" nogui
Which didn't work, and when I use this
C:\Program Files\Java\jre1.8.0_333\bin\jave.exe -Xmx16G -Xms8G -jar "Blightfall.jar" nogui
It recognizes C:\Program as a separate thing to the rest
