Major Hi everyone,
I'm trying to set up a multibranch pipeline on a repository containing a submodule that lives under the same Github account as my main repository. You'll find a screenshot of the job configuration below.
However, credentials from the parent (main) repo don't seem to be used to pull the submodule. Therefore, the "checkout scm" step fails with the following error:
Host key verification failed. fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.
Many thanks in advance for your help.

[JENKINS-46318] Parent remote credentials not used when updating submodules
Oh indeed. Jenkins was using a token based authentication while my .gitmodules was specifying to use SSH auth.
I changed the protocol to HTTPS in my .gitmodules and everything seems to work like a charm.
I'll close the ticket.
Many thanks Mark !
Wrong protocol was specified: Jenkins was trying to use HTTPS while the ".gitmodules" file indicated to use HTTPS.
Are your submodules defined to use the same protocol as the parent repository? For example, the submodule credentials implementation assumes that the same credential used for the parent (for example ssh protocol with private key) is used with all the submodules.
If you clone the parent repository with https but one of your submodules is referenced using ssh protocol (git@github.com or ssh://git.example.com/), then the credentials won't work.
