Hello,

I am trying to create a pixelmon server for me and my friends, however the forge server .jar (using forge 1.12.12 ver 2854) will not open. I am currently using java 8.311 as I have seen that the java version can be an issue. I can run the vanilla 1.12.12 server just fine, but for some reason the forge server will not open to even be able to get the eula. I am also not the best at command prompt or .bat files so was hoping to get some help on possibly how to fix. I have pasted logs below.

1.12 is no longer supported on this forum.
Please update to a modern version of Minecraft to receive support.
