Not Working

I tried looking at many other posts in this but non of them have seemed to work and I have spend 2 hours on this. I just want to mod my Minecraft. It keeps on saying that the workspace had an error being created, and this was apparently being caused by Gradle and that's all I was able to get to. I would love to know why there is so much that needs to happen and how I can fix this program not being created and how to create it if I have to manually.
