My .gitignore file, in a project file, contains /Carthage/Checkouts/, but Source Tree won't ignore the folder hierarchy that exists in that project folder at Carthage/Checkouts. I've also tried:
Carthage/Checkouts/
/Carthage/Checkouts/*
/Carthage/Checkouts/**
None of these cause Source Tree to ignore that folder hierarchy. What is the magic syntax that I'm missing?
