Jenkins: Failed to connect to repository

Question

I\'m trying to connect jenkins on a github repo.

When I specify the Repo URL jenkins return the following error message:

Failed to connect to

Answer 1

I faced a similar issue when I tried to connect jenkins in my Windows server with my private GIT repo. Following is the error returned in the source code management section of Jenkins job

Failed to connect to repository : Command "git.exe ls-remote -h ssh://git@my_server/repo.git HEAD" returned status code 128: stdout: stderr: Load key "C:\Windows\TEMP\ssh4813927591749610777.key": invalid format git@my_server: Permission denied (publickey). fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.

This error is thrown because jenkins is not able to pick the private ssh key from its user directory. I solved this in the following manner

Step 1

In the jenkins job, fill up the following info under Source Code Management

Repositories

Repository URL: ssh://git@my_server/repo.git
Credentials: -none-

Step 2

In my setup jenkins is running under local system account, so the user directory is C:\Windows\System32\config\systemprofile (This is the important thing in this setup that is not very obvious).

Now create ssh private and public keys using ssh-keygen -t rsa -C "key label" via git bash shell. The ssh private and public keys go under .ssh directory of your logged in user directory. Just copy the .ssh folder and paste it under C:\Windows\System32\config\systemprofile

Step 3

Add your public key to your GIT server account. Run the jenkins job and now you should be able to connect to the GIT account via ssh from jenkins.
