Can't cider-jack-in to projects with private git dependencies

[PavlosMelissinos]

Expected behavior

cider-jack-in works in projects with private git repos

Actual behavior

I'm getting some text in the nrepl-server buffer that asks for my passphrase but there's no interactive prompt, so I can't provide it to complete the process. Here's the exact message "prompt" as it appears in the nrepl buffer:

Cloning: [email protected]:org/private-repo-name.git

Enter passphrase for key '/home/pavlos/.ssh/id_ed25519': 

Steps to reproduce the problem

Create a deps.edn with the following contents

{:deps {foo/bar {:git/url "[email protected]:org/private-repo-name.git"
                 :sha     "sha"}}}

where org/private-repo-name is a private repo

Run M-x cider-jack-in

In case anyone else is facing this, here are some workarounds:

1. Spawn a standalone cider/nrepl server and cider-connect to it, as described in the docs
2. Download the dependencies with clojure -P and then rerun cider-jack-in

Hi!

Thanks much for the report.

I'll try to repro it, anyway could you please provide the exact prompt text?

[PavlosMelissinos]

Good point, it's:

Cloning: [email protected]:org/private-repo-name.git

Enter passphrase for key '/home/pavlos/.ssh/id_ed25519': 

Like I said it only appears in the ~REPL~ nrepl-server buffer (and it's not interactive) I've added it to the initial description too

Are you able to git-clone the same repo using e.g. Magit?

If not, it could indicate a generalized issue in your Emacs setup, such that ssh-add isn't being correctly invoked.

Example:

[...] You can confirm this by running eval $(ssh-agent); ssh-add ~/.ssh/id_rsa in a terminal, and then in the same terminal emacs &.

That solution isn't exactly ergonomic, but it would be a start.

Please try that specific approach for CIDER and/or Magit, allowing us to discard hypotheses.

Thanks - V

Are you able to git-clone the same repo using e.g. Magit?

Yes! If I delete the cache from .gitlibs and run magit-clone directly I get the correct prompt (same message but interactive)

[vemv]

Thanks!

To be clear, is your expected workflow entering the passphrase each time? It would make sense, although perhaps in your terminal emulator you don't have to?

[PavlosMelissinos]

is your expected workflow entering the passphrase each time

I believe that depends on how the ssh agent is set up. So it doesn't happen always (I think) but:

• when ssh-agent needs a passphrase I expect emacs/CIDER to ask for the user input correctly (magit-clone does so, so I assume it's caused by something that happens somewhere between the git and cider abstraction levels)
• when a passphrase isn't necessary, I expect CIDER to be able to clone the repo and then start the REPL (neither happens in my case, CIDER gets stuck "waiting" for user input that will never come).
