I'm very new with Jenkins, and I'm trying to learn how to use it. I have setup the Jenkins on my small Windows-based server, and I have another server (raspberry) where I have initialized a small git project. When I try to add this git repository to the Jenkins, it can not connect to it no matter what. Here's what I have tried so far.
I can check, that the connection is working to the git server by using git ls-remote -h ssh://gitserver#192.168.50.152:22/home/gitserver/GitProject/.git command from any computer within the network, and I get a response after giving my password. I have saved this password as a "Username with password" -kind to Jenkins > Manage Jenkins > Credentials. Then, I have selected this from the Credentials drop down, but all I get is this error: "Failed to connect to repository : Error performing git command: git.exe ls-remote -h ssh://gitserver#192.168.50.152:22/home/gitserver/GitProject/.git HEAD"
Interesting part is, that if I try that command given with the "HEAD" at the end, I get just empty line, but no errors. Could this be an indicator to some kind of an issue? Here's a picture of the configuration. Am I doing something wrong? I have SSH authentication right now via password and ssh-public key. I have tried the SSH-public key as a credential, but no luck.
I'm very new to Jenkins, and just starting to learn, but I could not find an answer to this. Many articles were just pointing out how to connect to GitHub project, but I want to connect to this local project sitting on a raspberry pi, as an exercise.
Ok, the issue was with Jenkins and specifically with the SSH plugin it is using to connect. After updating everything, and Jenkins restarted, the connection is now working, and I can confirm this by clicking the "Build Now", and checking the Build log, Jenkins did fetch the info from the Raspberry server, and it is now sitting at the data-folder of this server!
So, for the rest of the people having this issue, try to update all plugins and then restart the Jenkins.

I'm trying to configure the git repository in Jenkins, I followed all steps on github documentation but I had the bellow error on my application .
I've configured the agent, then I put the ssh url on jenkins.
I've configured the ssh on github as well.
Failed to connect to repository : Command "git ls-remote -h -- git#github.com:user/maven-project.git HEAD" returned status code 128:
stdout:
stderr: git#github.com: Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists
The issue was solved that way
In windows, Jenkins will use the the SSH key of the user it is running as, which is located in the %USERPROFILE%.ssh folder ( on XP, that would be C:\Documents and Settings\USERNAME.ssh, and on 7 it would be C:\Users\USERNAME.ssh). Therefore, you need to force Jenkins to run as the user that has the SSH key configured. To do that, right click on My Computer, and hit "Manage". Click on "Services". Go to Jenkins, right click, and select "Properties". Under the "Log On" tab, choose the user Jenkins will run as, and put in the username and password (it requires one). Then restart the Jenkins service by right clicking on Jenkins (in the services window), and hit "Restart".
Jenkins does not support passphrases for SSH keys. Therefore, if you set one while running the initial Github configuration, rerun it and don't set one.
I'm going to say you don't have the credentials configured properly as you did not mention that.
A similar Stack Overflow response is here, for a slightly different worded error. Similar issue here.
The Jenkins site and others have good examples on setting up Jenkins with GitHub.
I'm attempting to clone a remote GitHub enterprise repository and am running into the following error after adding my remote repo's URL to the Git Plugin in my Jenkins configuration:
Failed to connect to repository : Command "git.exe ls-remote -h https://<<server>>/M/AS.git HEAD" returned status code 128:
stdout:
stderr: fatal: unable to access 'https://<<server>>/M/AS.git/': Received HTTP code 502 from proxy after CONNECT
Firs of all You Need to setup github with jenkins in below section also
Go to Github --> click on profile dropdown --> settings --> devloper settings --> personal access token -->
generate new token --> select all scopes --> copy the token
Then go to Jenkins --> manage Jenkins --> github settings --> add user --> Select secret text--> paste the token
Then Test the git-hub connection by clicking test button If its Successful the Jenkins will ready to clone the GitHub repository
And also add Webhooks, Integrations & Services in GitHub
Make sure you have generated Git API Token in Git repository and added the same in the Jenkins Credentials.
If the is done, I don't think there will be any issue in connecting Git to Jenkins.
Also you can test if your Git server is able to ping your Jenkins server. (If you are running your own Git and Jenkins).
All the best.
Check your failed job environment variables.
If there is no environment variable named NO_PROXY, set one in the configuration of your JENKINS job:
NO_PROXY=.mycompany.com
Here, I assume your GitHub Enterprise has an URL like myserver.mycompany.com (replace (mycompany.com by your own)
That will avoid Jenkins trying to access the remote server through the proxy.
If you are running from a VM, make sure you install the package 'git-core'.
You must have git installed in the machine where jenkins is running
I had the same issue and for me it helped a restart for the machine where it was installed Jenkins.
I deploy Jenkins and GitLab using Docker (locally), both are connected with each other.
One of the problems (not very important) is with SSH. I create ssh key inside Jenkins container and set it to GitLab, but when Jenkins try to checkout the repository throws "Permission Denied". So, executing Jenkins bash, try to run git command and what's happen? GitLab container needs a password for access. Searching, and trying to do as a virtualized server, no works. Whatever, I solved using user and password (I don't like, but works).
The important problem. I don't have any problem creatin, and running, a job (using pipelines). The job download the world from GitLab and send the result to GitLab. The problem, after add a webhook with Jenkins URL to GitLab, push something but nothing happens in Jenkins, not trigger the job.
Anyone can help me?
Thanks!!
Is your webhook working correctly ?? are you able to send/receive request and response, if not refer to
Github webhook URL config issue? How to fix it?
When you push does it trigger a request ? can you try hitting it with postman if you do have a request. If you can provide more information, then it will be helpful :)
There are lots of question on here about Permission denied (publickey) errors when using the Jenkins git plugin.
Can someone explain the authentication flow this plugin uses to check out a repository? I can't find a good description on the plugin page.
I want to just SSH into the build slave, checkout the repository there, then run my job, but clearly that is not how it works.
I guess I could add my credentials to the jenkins master, but I dont want any code there. I want it on my build slave.
Issue has nothing to do with git really. As their documentation states, it relies on git runtime which in its turn relies on system environment when it comes to secure connections. Ssh requires client to have valid key to connect and fails to that message if client does not provide one. Without any additional actions, key is not injected into environment, so client could not provide any valid key.
What you actually can use is ssh agent plugin. That allows to add key to ssh-agent on slave that will be catched up by git.
I want to deploy my created war automatically to /tomcat/webapps from jenkins scp plugin.
In jenkins ->Manage Jenkins ->configure system
Hostname-deploy port-22 repository- "ipaddress:8080"/usr/bin/scp

password-jenkins
In jenkins->new job ->configure
scp site - deploy
file to upload
source - http://"ip:8080"/var/lib/jenkins/workspace/WebWarDemo/source/**
destination - http://"ip:8080"/usr/share/tomcat6/webapps/
above is my configuration for scp plugin but i am getting error in first configuration as shown.
but when i tried to run the another error is "jenkins scp com.jcraft.jsch.jschexception auth cancel" i tried so many times changing user name no effect plz suggest anything
I am entering username and password of jenkins server user.
Make sure of the following things:
The user with which you are trying to connect to Repository server has "WRITE" access.
SSH connection has been established between the twos servers with public keys of the respective users
Login to jenkins as jenkins user and run the following
ssh repouser#repository server
What do you get?
Let me know if you have ensured these. Will take it ahead from there
