Mods Not Working

[cooldog980]

I'm having issues. I just installed Minecraft Forge on my Linux server, but every time I try to add mods the server crashes. I have the Recommended version of Forge installed. I download a mod and added it to the "Mods" Folder and it gives the same error no matter what the mod is. It works as long as I don't have any Mods in the Mods folder. Here's what happens when I try to start the server:

Below is the server crash report:

A detailed walkthrough of the error, its code path and all known details is as follows:

I'm assuming it has something to do with:

[16:59:25] [Server thread/FATAL] [ne.mi.fm.ModLoader/LOADING]: File /home/shon/Desktop/mc-creative/mods/BuildingGadgets-2.8.2.jar constructed 0 mods: [], but had 1 mods specified: [buildinggadgets]

 But I can't seem to find that error anywhere on Google. Any help would be greatly appreciated. Thanks in advance!

2.8.2 is a 1.12.2 version of the mod.

One of the devs seems to have not cleaned their workspace when switching between MC versions.
