When I start create my first build definition for Team project I face the following error,
TF225001: Creating a build definition requires a build controller be defined for this team project collection. There may not be any controller configured or you may not have permission to view them
So after little search I figure it out it will be as the following
So now if you create a new build definition you should see the following screen
but the problem that I didn’t choose network service so I have the following error “Cannot start service TFSBuildServiceHost on computer”
and after good search on event log I found that this because failure of the login so I change it to be a network service as the previous configuration.
