The .gitignore setting for the .idea folder of Jetbrains Rider's does not work

Question

I am currently working on a game project for Android using Unity and Rider on Windows10. Git administration is using Github Desktop.

After completing the game production, I tried to set up .gitignore to upload to Github, I connected to gitignore.io and selected windows, unity, jetbrains + all, and then entered .gitignore in my .gitignore which is displayed on the screen. The link to the code is https://www.gitignore.io/api/unity,windows,jetbrains+all.

The code below is the .gitignore code I wrote down.

However, some of the files in the .idea folder are different from the .gitignore settings. So I left this question. As far as I know, the subdirectory of the .idea folder should not be registered with git, but I wonder if it is normal to see some files. If this is not normal, it will ask you if you want to add all the .idea folder sub-lists to .gitignore.

The picture below is a picture taken from Github Desktop.

I will be waiting for a good answer. Thanks for reading.

Answer 1

The reason that this folder is not ignored since it stores the configuration of your project and due to that it's not part of the default .gitignore

You can fix it in no time.

Explaining how to do from the command line, can be done via IDEA as well.

# Once the files are committed adding them to .gitignore will not help,
# you must remove them from the index
# Remove the file from the repository
git rm --cached .idea/

# now update your gitignore file to ignore this folder
echo '.idea' >> .gitignore

# add the .gitignore file to your index
git add .gitignore

git commit -m "Removed .idea files"
git push origin <branch>

Answer 2

echo ".idea/*" >> ~/.gitignore
git config --global core.excludesfile ~/.gitignore
