java - git ignore doesn't ignore already submitted files? -

this .gitignore file:

src/main/resources/* !src/main/resources/input 

in past submitted few files under resources folder.

now see files still monitored git (as changed) if under src/main/resources/foo1

how come git ignore don't hide these files git status?

gitignore governs addition of new files, files tracked continue tracked.

to remove them git keep them in filesystem, use --cached option of rm:

git rm -r --cached src/main/resources
