1.12.2 Forge Server won't launch

[Bloem]

I've been trying to make a Modded server for me and my friends to play on. At first the server would work but I couldn't place modded blocks after identifying that it was launching from the bundled minecraft server .jar, I changed it launch from forge but now the server won't start and this is what I'm getting:

 

C:\Users\bloem\OneDrive\Desktop\Forge Server>java -Xmx6144M -Xms6144M -jar forge-1.12.2-14.23.5.2854.jar nogui
