Permission denied (publickey) when setting up Jenkins

I am setting up Jenkins on a Win 2008 server machine and am having some trouble configuring Jenkins to connect to GitHub. I get the following error:

Command "git.exe fetch -t git@github.com:USER/REPO.git +refs/heads/*:refs/remotes/origin/*" returned status code 128: Permission denied (publickey).
fatal: The remote end hung up unexpectedly

ERROR: Could not fetch from any repository

Things I Have Checked


  • The Jenkins service is running under my username.

  • I changed my SSH key so it no longer has a password.

  • I have verified my SSH key is valid by executing the same command as Jenkins using msysgit.

  • Verified all my paths are correct.



Jenkins Configuration Settings


  • Jenkins 1.418

  • GitHub plugin 0.5

  • Git plugin 1.1.9



msysgit Works but CMD Prompt Does Not
When I navigate to a valid repo and execute the command from the DOS prompt, it also fails.

Do you have any idea what I may be missing?

Thanks for your help.

Answer

As I commented, specifying the HOME environment variable is key, when using ssh protocol.
Since Windows doesn't have a HOME, you need to define it explicitly, to whatever directory you want.

However, Vestnik comments:

I've specified to override HOME on the windows slave node to point it to C:\jenkins.
I've put correct id_rsa under the C:\jenkins\.ssh but still have this issue.
My slave agent running as service under SYSTEM account.

Two advices:

  • you need to make your slave display 'set' in order to check if HOME is defined when used with the SYSTEM account.
    If it is not, that may mean you need to add that variable to the "system environment variables", not the "user environment variables".

display env from the job definition

  • Don't forget to have both id_rsa and id_rsa.pub in the %HOME%\.ssh directory: you need both public and private ssh keys. (as mentioned in "git clone with ssh issue")

If you have a parametrized build, you also can define HOME that way and check if your slave picks up the right value for HOME:

define custom variables
