Intellej idea creating files and automatically push it to git

Hello @...

It looks like you have "Add silently" checked under Preferences | Version Control | Confirmation this is why those files and folders were added to Git automatically.

If you want to ignore a file that is already checked in, you must untrack the file before you add a rule to ignore it. Please run the following command to untrack a file:

$ git rm --cached FILENAME

or for a folder:

$ git rm -r --cached path_to_your_folder/

Then you can add files and folders to .gitignore

Please see the following article for more info on what files must be ignored:
