Problem when trying to connect to GitHub from a Windows slave

[Sébastien Hinderer]

Dear all,

Recently, I wanted my slaves to fetch our GitHub repository through
authenticated ssh coneections rather than through HTTPS unauthenticated
connections.

I created the appropriate Jenkins credential with ssh keys, replaced the
HTTPS URL of the repo by an ssh-based one and requested the use of the
newly created credential.

On our Unix machines everything works like a charm.

On our Windows machines, though, I get an "invalid format" message while
trying to read a .key file.

In case it's useful, our Windows hosts are running git 2.17.0 and
OpenSSH 7.8p1.

Many thanks in advance for any hint!

Sébastien.

Hello

Have you tried cloning manually using the ssh key on windows?

Also, what username have you configured for your git credential on Jenkins?

I faced ssh issues on windows because of change in SSH/GIT and it was necessary to set credential username to 'git' instead of the real github username. See https://issues.jenkins-ci.org/browse/JENKINS-50573

Yes, and it worked.
Sorry I forgot to mention this.

The GitHub user name. But the 'git@' part in the URL of the repository.
Additionnally, as I mentionned, this setting works perfectly well for
the Unix machines.

Thanks! Actually, my GitHub plugin is up-to-date so I'd expect this to
be fixed, right?

Also my error message is different from the one reported in the bug,
mine explicitly mentions an "invalid format" in the keyfile.

But many thanks for helping out, I really appreciate and hope we willl
find the problem!

What do you mean by git bash ?

And hten of course the public key needs to be added on GitHub. Well
since the manual clone worked I'm a bit reluctant to do all this, I have
to say.
