Workspace not compiling Properly (Custom .Java armor files)

Recently started to learn java with zero coding experience using eclipse, Trying to make a mod with custom armor models from tabula now exported as .Java files. I moved to Mcreator because it seemed like a very easy way to start learning Java whilst producing mods for minecraft. Now I'm getting an error while trying to test my custom armor.

"Your Workspace contains mod elements that don't compile properly."

Here is the gradle error log.
