.gitignore Não Funciona

Even if you haven't tracked the files so far, git seems to be able to "know" about them even after you add them to .gitignore.

NOTE : First commit your current changes, or you will lose them.
Then run the following commands from the top folder of your git repo:

Copygit rm -r --cached .
git add .
git commit -m "fixed untracked files"
