gradle workspace fail please help?

Hi, whoever is reading this, 

yesterday, I found out about mcreator and downloaded it, because I wanted to create some mods, but it keeps failing at building the gradle, and I tried some things I found online, such as deleting caches, and deleting the gradle folder, and it still does not work, can anyone help?
