I realize that this has already been looked at, but it's closed so I thought I'd make a new issue just to put it on the page.

Version: 1.16.5
cloned straight from Github

I tried compiling from source on manjaro, no luck. I try changing java versions, deleting and reinstalling the folder, no dice. I go into a Pop! OS VM and try JDK 11 and JDK 8, no luck. when I read the original issue, it said that it was not an issue with tinkers construct so I would like to know how I am supposed to do it because nothing seems to be working, and it gives me the error that some of the features have been depreciated during building.

I got an error that looked nearly the exact same in the VM.

I cannot tell what I'm doing wrong, and I am fairly new. any help would be appericiated.

You are building from source without knowing how to set up a mod workspace.

The mod will be released when it is ready, be patient like everyone else.
