I'm trying to setup Jenkins on my mac mini in order to pull my iOS project source code from BitBucket and build it automatically. I've already gone through the major well know problems generating the ssh keys,uploading them in BitBucket,performing an ssh connection by console for adding the host to the well know list (you can find all my adventure here and here). Now,there are 3 user in my system: A,B and Shared. When I installed Jenkins it automatically placed itself in Shared, but I generated the ssh keys with the user A. So just to be clear In the A home directory there is an .ssh directory with public and private keys.

When I try to run by Jenkins job I get this error message:

As you can see it fails when Hudson try to run the GIT command. The odd things is that if I try to run

/usr/local/git/bin/git clone --progress -o origin [email protected]:myuser/myproject.git /Users/Shared/Jenkins/Home/jobs/myprojectAdHocBuild/workspace

In my console, it works fine (after fixing a small problem relative the folder write permission with chmod)

I found a post reporting a similar error which names a number of possible options but I'm not sure how to perform correctly these operations on my console. It looks like Jenkins is trying to run a command with a user which doesn't have permission to retrieve the appropriate keys from my .ssh directory.Not really sure.Maybe this output can help:

MacMini:~ myuser$ ps axu | grep "/jenkins"

I really hope to fix this problem, because I would like to write a very detailed tutorial with all the information I found disseminated around the web.
