Server won't run with .bat file

[SirThiccalot]

I'm trying to run a forge server on my own pc so I can play with a few plugins and mods, I can run the server just fine when I run the .jar for it, but that limits it to ~200MB of ram, and I want to give it at least 2GB, so I made a .bat file with this: "java -Xmx2G -jar forge-1.12.2-14.23.5.2838-universal.jar" code, but when I run the .bat file it opens for a split second and then immediately closes. Any help is appreciated
