GUI Causing errors, tried everything. 2020.4

I have a GUI for a crafting table I made and after watching all the videos it still does not function right. I have a sharable zip to give.

Here is teh sharable zip file (mediafire because i don't know how to upload to this website) 


Also here is the console text.

Override is not a repeatable annotation type @Override

In some cases, Gradle caches that make sure the build process does not take too long can get corrupted. In such a case, go to:

<your user home folder>/.mcreator/gradle

In this folder, there is a folder called caches. Delete this folder and open MCreator again. Next build will take a bit longer as caches need to be rebuilt. If you can not delete all files in this folder (which is necessary), reboot the computer first to remove any potential file locks.

If this is not enough to make things work, delete the entire gradle folder, not just caches, and try again.

If even this fails, try to delete the entire <your user home folder>/.mcreator/gradle folder, create a new workspace with the same generator version as the version of the workspace failing, after the setup of this new workspace is done, open your current workspace, and click Build & run -> Build workspace, then Build & run -> Reload gradle project and then Build & run -> Regenerate code and build.
