Okay so, this issue is like everyone elses, eeexept I cant actually fix it with the solution that everyone else gets. So I type out java -jar BuildTools.jar --rev latest and run it. It says that I only have 247M, I then run java -Xmx512M -jar BuildTools.jar --rev latest and it goes through Patching or whatever and then it stops at WorldUpgrader.patch and then outputs Rebuilding Forked projects.... It then reverts all changes and says Error compiling Spigot. Please check the wiki for FAQs. I have added a picture for reference on the error. I am not sure on how to fix it.

Edit: I intsalled the newest version on Git and it still outputs the same issue.
Fix: Use Git Bash as Console. I didnt notice they said that.
