Can't pull a private repository

[i-am-the-slime]

steps

sbt or Giter8 version:

g8 0.16.2

problem

Trying to run sbt new or g8 on a private repo leads to:

> g8 ssh://git@github.com/my-org/my-template.g8.git
ssh://git@github.com/my-org/my-template.g8.git: Cannot log in at github.com:22

expectation

It should not fail to log in (since cloning the repo works just fine)

I wonder if this is related to using https://github.com/maxgoedjen/secretive over ssh-agent.
I think it would be nice if this project could just call out to the git process instead of using a Java implementation of git.
