[1.12.2] Trouble loading up Minecraft Environment in Eclipse

Hello!

I'm not sure if this is the right place to post this, but I made an account just for this so let's hope so.

I'm trying to get into modding and I've been following some modding tutorials. But I'm at the bare basics step - a blank mod with no actual content in it, just the basic initialization steps and references, and trying to run it in the Eclipse IDE.

However, it keeps on failing to load up the minecraft environment when I hit the "run" button. This is my Console output: https://pastebin.com/DuG0QMSx

I looked at it with debug and it seems the issue is something about minecraft not being able to get my System Time or something? I'm not entirely sure what that means, but google searching my issue has yielded no results.

Any help on how to fix this would be great!
