Error installing Gradle 2020.2. Please help me. I'm looking for a portable build or something similar.

Hello everyone I ran into a Gradle issue at Mcreator 2020.2. I am developing a map in minecraft on version 1.12.2. I needed to create a mod for this version and I downloaded MCreator 2020.2. I installed everything, but bam, when creating a working environment, there was an error with installing Gradle. As I understood it, the mistake was that gradle couldn't install flowerforge like and gradleforge, well, something like that, from the official minecraftforge website (I may be mistaken in the names somewhere, sorry). So I've already contacted everywhere and searched in communities and even with chatgpt. Everyone says that I tried to install it manually, but it didn't help. MCreator just creates another new folder and uploads these files there in a new way. And I'm asking for your help, please, please help. If you have a ready-made gradle folder or .mcreator . If there is, please write. Well, or you can help me in some other way, please write to me, I beg you. please!!!
