I am trying to use git as Source Code Management in jenkins. Since I am using git provided by google, I am using "Google Service Account from private key" credential to setup git.

I added that credentials at the top level into global credentials. However when I create new item to setup my project, and select git as my "Source Code Management" I do not see my credentials in the dropdown.

There is an option to add new credential on the same page, but when I add it, I still can not see it in the dropdown. What am I missing?
