How to put dir .apt_generated to gitignore

Question

I put to the .gitignore file

.apt_generated

but everytime after recompiling the project eGit in Eclipse and git status -s show that the files in .apt_generated are changed.

Answer 1

If you added it to the .gitignore after you committed it once, you need to remove it from the index by typing

git rm --cached .apt_generated
