.gitignore is ignored by Git

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.

WARNING: First commit or stash your current changes, or you will lose them.

Then run the following commands from the top folder of your Git repository:

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

If it seems like Git isn't noticing the changes you made to your .gitignore file, you might want to check the following points:

• There might be a global .gitignore file that might interfere with your local one

• When you add something into a .gitignore file, try this:

  git add [uncommitted changes you want to keep] && git commit
  git rm -r --cached .
  git add .
  git commit -m "fixed untracked files"
  

• If you remove something from a .gitignore file, and the above steps maybe don't work,if you found the above steps are not working, try this:

  git add -f [files you want to track again]
  git commit -m "Refresh removing files from .gitignore file."
  
  // For example, if you want the .java type file to be tracked again,
  // The command should be:
  //     git add -f *.java
  

Fixed. OK, I created the .gitignore file in Notepad on Windows and it wasn't working. When I viewed the .gitignore file on Linux it looked like organised gibberish - perhaps Notepad had written out Unicode rather than ASCII or whatever 8-bit is.

So I rewrote the file on my Linux box, and when I pulled it back into Windows it works fine! Hurrah!
