Intellij Annotate Option Grayed Out

Question

I am trying to look at who changed a line in Intellij 15. I know I can use git blame but I want to learn how to do it correctly in intellij. I am right clicking on the line numb

Answer 1

The answer by @activedecay let me in the right direction. In my case, I have a multi-module project - each has a separate git repo - but we're all in the same workspace.

In my case, Intellij IDEA 2017.2, the Preferences -> Version Control panel shows a listing of all the project roots. The module with the disabled "Annotate" option was in the "Unregistered Roots" section.

To fix the problem, I selected the module and pressed the "+" icon in the lower toolbar to register the module root with Intellij VCS. The change is immediate and the "Annotate" options becomes available.
