Turn off Intellij auto adding to VCS/Git
On Ubuntu 16.04 - Go to:
File -> Settings -> Version Control -> Confirmation -> When Files are created
Here you can configure how IDEA behaves for when a file is added or deleted (and other scenarios), options: - silently adds file to Git or display popup with options or if it should do nothing
select option: "Do Not Add"
Preferences |> Version Control |> Confirmation is the only place to configure this behavior.
This is a common functionality, not only for git. I have never seen it disabled. Does it happen for all controls in the Confirmation node? What about other options under Version control? Doesn't IDE restart help?
