I have a git repo which has one submodule. Both belong to a team on BitBucket. My jenkins machine is a AWS windows server with the git plugin. I am using SSH keys for authentication. I have three jenkins jobs. One clones the main repo. This is successful. One clones the second repo on its own (the repo which will be used as a submodule). This is also successful. In my third build job I tell jenkins to recursively update the submodules. This fails and says public-key error. How can this be the case if I can clone the repo on its own?

This is was a known bug in jenkins: https://issues.jenkins-ci.org/browse/JENKINS-20941 but it has now been fixed, update your Git plugin to resolve the issue.
If updating is not possible, as a workaround, you could put the key in jenkins-users .ssh folder.
Based on the earlier answers here, I re-prioritized upgrading my client's Jenkins. Now they are on Jenkins 2.41 with Git plugin 3.0.1 and before additional configuration this did not fix the issue. I found the configuration to be a little tricky:
- Add top-level repository to Source Code Management -> Git
- Select the "Additional Behaviours" Add button
- Select "Advanced sub-modules behaviours"
- I tested with only "Recursively update submodules" and got the "Permission denied" error (see bottom*)
- However, I now select both "Recursively update submodules" and "Use credentials from default remote of parent repository" in Jenkins 2.41
Once I select both options, it uses the credentials I had configured for the top-level repository and everything works for me. Here is what the dialog looks like in 2.41 with Git plugin 3.0.1:

* Here is the essence of my "Permission denied" error:
Cloning into 'thirdparty'...
stderr: Permission denied (publickey). fatal: The remote end hung up unexpectedly Clone of 'ssh://hg@bitbucket.org//thirdparty' into submodule path 'thirdparty' failed
PS Just before posting, I did my usual double check to make sure I'm not duplicating an answer. In this case, I see that @danielfn's comment points to something that is nearly identical to my answer, but 1. this didn't help me and I ended up figuring it out by trial and error and 2. it is StackOverflow policy to post answers here rather than referencing external links.
As an alternative, you may use 'Source Code Management' - 'Multiple SCMs' to manually configure all the sub-modules and add 'Additional Behaviours' - 'Check out to a sub-directory' for each one.
It seems that they have fixed it with the versions git client plugin 1.20.0-beta1 and git plugin 2.5.0-beta1. However, they can only be added to Jenkins by specifying to pull updates from the experimental update center.
