Export/import jobs in Jenkins
JenkinsJenkins Problem Overview
Is it possible to exchange jobs between 2 different Jenkins'? I'm searching for a way to export/import jobs.
Jenkins Solutions
Solution 1 - Jenkins
Probably use jenkins command line is another option, see https://wiki.jenkins-ci.org/display/JENKINS/Jenkins+CLI
- create-job: Creates a new job by reading stdin as a configuration XML file.
- get-job: Dumps the job definition XML to stdout
So you can do
java -jar jenkins-cli.jar -s http://server get-job myjob > myjob.xml
java -jar jenkins-cli.jar -s http://server create-job newmyjob < myjob.xml
It works fine for me and I am used to store in inside my version control system
Solution 2 - Jenkins
A one-liner:
$ curl -s http://OLD_JENKINS/job/JOBNAME/config.xml | curl -X POST 'http://NEW_JENKINS/createItem?name=JOBNAME' --header "Content-Type: application/xml" -d @-
With authentication:
$ curl -s http:///<USER>:<API_TOKEN>@OLD_JENKINS/job/JOBNAME/config.xml | curl -X POST 'http:///<USER>:<API_TOKEN>@NEW_JENKINS/createItem?name=JOBNAME' --header "Content-Type: application/xml" -d @-
With Crumb, if CSRF is active (see details here):
Get crumb with:
$ CRUMB_OLD=$(curl -s 'http://<USER>:<API_TOKEN>@OLD_JENKINS/crumbIssuer/api/xml?xpath=concat(//crumbRequestField,":",//crumb)')
$ CRUMB_NEW=$(curl -s 'http://<USER>:<API_TOKEN>@NEW_JENKINS/crumbIssuer/api/xml?xpath=concat(//crumbRequestField,":",//crumb)')
Apply crumb with -H CRUMB
:
$ curl -s -H $CRUMB_OLD http:///<USER>:<API_TOKEN>@OLD_JENKINS/job/JOBNAME/config.xml | curl -X POST -H $CRUMB_NEW 'http:///<USER>:<API_TOKEN>@NEW_JENKINS/createItem?name=JOBNAME' --header "Content-Type: application/xml" -d @-

Jenkins has a rather good wiki, albeit hard to read when you're new to CI software...
They offer a simple solution for moving jobs between servers
The trick probably was the need to reload config from the Jenkins Configuration Page.
Update 2020.03.10
The JenkinsCI landscape has changed a lot... I've been using Job DSL for a while now. We have a SEED Job that generates the rest of the jobs.
This helps us both recreate or move for the Jenkins server whenever needed :) You could also version those files for even more maintainability!
Solution 4 - Jenkins
In a web browser visit:
http://[jenkinshost]/job/[jobname]/config.xml
Just save the file to your disk.
Solution 5 - Jenkins
There's a plugin called Job Import Plugin that may be what you are looking for. I have used it. It does have issues with importing projects from a server that doesn't allow anonymous access.
For Completeness: If you have command line access to both, you can do the procedure already mentioned by Khez for Moving, Copying and Renaming Jenkins Jobs.
Solution 6 - Jenkins
In my Jenkins instance (version 1.548) the configuration file is at:
/var/lib/jenkins/jobs/-the-project-name-/config.xml
Owned by jenkins user and jenkins group with 644 permissions. Copying the file to and from here should work. I haven't tried changing it directly but have backed-up the config from this spot in case the project needs to be setup again.
Solution 7 - Jenkins
Go to your Jenkins server's front page, click on REST API at the bottom of the page:
> Create Job
To create a new job, post config.xml
to this URL with query parameter name=JOBNAME
. You need to send a Content-Type: application/xml
header. You'll get 200
status code if the creation is successful, or 4xx/5xx
code if it fails. config.xml
is the format Jenkins uses to store the project in the file system, so you can see examples of them in the Jenkins home directory, or by retrieving the XML configuration of existing jobs from /job/JOBNAME/config.xml
.
Solution 8 - Jenkins
Job Import plugin is the easy way here to import jobs from another Jenkins instance. Just need to provide the URL of the source Jenkins instance. The Remote Jenkins URL can take any of the following types of URLs:
-
http://$JENKINS
- get all jobs on remote instance -
http://$JENKINS/job/$JOBNAME
- get a single job -
http://$JENKINS/view/$VIEWNAME
- get all jobs in a particular view

Thanks to Larry Cai's answer I managed to create a script to backup all my Jenkins jobs. I created a job that runs this every week. In case someone finds it useful, here it is:
#!/bin/bash
#IFS for jobs with spaces.
SAVEIFS=$IFS
IFS=$(echo -en "\n\b")
for i in $(java -jar /run/jenkins/war/WEB-INF/jenkins-cli.jar -s http://server:8080/ list-jobs);
do
java -jar /run/jenkins/war/WEB-INF/jenkins-cli.jar -s http://server:8080/ get-job ${i} > ${i}.xml;
done
IFS=$SAVEIFS
mkdir deploy
tar cvfj "jenkins-jobs.tar.bz2" ./*.xml
Solution 10 - Jenkins
Jenkins export jobs to a directory
#! /bin/bash
SAVEIFS=$IFS
IFS=$(echo -en "\n\b")
declare -i j=0
for i in $(java -jar jenkins-cli.jar -s http://server:8080/jenkins list-jobs --username **** --password ***);
do
let "j++";
echo $j;
if [ $j -gt 283 ] // If you have more jobs do it in chunks as it will terminate in the middle of the process. So Resume your job from where it ends.
then
java -jar jenkins-cli.jar -s http://lxvbmcbma:8080/jenkins get-job --username **** --password **** ${i} > ${i}.xml;
echo "done";
fi
done
Import jobs
for f in *.xml;
do
echo "Processing ${f%.*} file.."; //truncate the .xml extention and load the xml file for job creation
java -jar jenkins-cli.jar -s http://server:8080/jenkins create-job ${f%.*} < $f
done

For those of us in the Windows world who may or may not have Bash available, here's my PowerShell port of Katu and Larry Cai's approach. Hope it helps someone.
##### Config vars #####
$serverUri = 'http://localhost:8080/' # URI of your Jenkins server
$jenkinsCli = 'C:\Program Files (x86)\Jenkins\war\WEB-INF\jenkins-cli.jar' # Path to jenkins-cli.jar on your machine
$destFolder = 'C:\Jenkins Backup\' # Output folder (will be created if it doesn't exist)
$destFile = 'jenkins-jobs.zip' # Output filename (will be overwritten if it exists)
########################
$work = Join-Path ([System.IO.Path]::GetTempPath()) ([System.IO.Path]::GetRandomFileName())
New-Item -ItemType Directory -Force -Path $work | Out-Null # Suppress output noise
echo "Created a temp working folder: $work"
$jobs = (java -jar $jenkinsCli -s $serverUri list-jobs)
echo "Found $($jobs.Length) existing jobs: [$jobs]"
foreach ($j in $jobs)
{
$outfile = Join-Path $work "$j.xml"
java -jar $jenkinsCli -s $serverUri get-job $j | Out-File $outfile
}
echo "Saved $($jobs.Length) jobs to temp XML files"
New-Item -ItemType Directory -Force -Path $destFolder | Out-Null # Suppress output noise
echo "Found (or created) $destFolder folder"
$destPath = Join-Path $destFolder $destFile
Get-ChildItem $work -Filter *.xml |
Write-Zip -Level 9 -OutputPath $destPath -FlattenPaths |
Out-Null # Suppress output noise
echo "Copied $($jobs.Length) jobs to $destPath"
Remove-Item $work -Recurse -Force
echo "Removed temp working folder"
Solution 12 - Jenkins
It is very easy just download plugin name
Enter the URL of your Remote Jenkins server and it will import the jobs automatically
Solution 13 - Jenkins
The most easy way, with direct access to the machine is to copy the job folder from first jenkins to another one (you can exclude workspaces - workspace
folder), because the whole job configuration is stored in the xml file on the disk (config.xml
in the job path folder)
Then in the new jenkins just reload configuration
in the global settings (admin access is required) should be enough, if not, then you will need to restart Jenkins tool.
Another way can be to use plugins mentioned above this post.
edit:
- in case you can probably also exclude
modules
folders and in case of pipelines as well shared libraries folders likeworkspace@libs
Solution 14 - Jenkins
config.xml
then use the same to import:
If you have exported the curl -k -X POST 'https:///<user>:<token>@<jenkins_url>/createItem?name=<job_name>' --header "Content-Type: application/xml" -d @config.xml
I am connecting via HTTPS and disabled certificate validation using -k
.
-
This is how to generate user api token on Jenkins.
-
Jenkins REST API details can be seen if you click the link with same name at bottom right corner of your Jenkins instance.

2021 and the export & import process are a pain!!
If you have shell access to both jenkins instances: the old and new, follow these steps to perform a success jobs migration:
In your old jenkins
- locate the jenkins home in your old jenkins. Usually /var/lib/jenkins. If you are using bitnami : /opt/bitnami/jenkins
- inside jenkins home, enter to jobs folder
- you should see folders with the name of your jobs. Inside of these folder, you just need the config.xml
- backup all the required jobs. Just the folder and its config.xml. There are a lot of other files that is not required.
In your new jenkins:
- locate the jenkins home
- copy your jobs (previous backup) to the jobs folder
- ensure that these new folder have the user "jenkins" as owner. If not use this: chown jenkins:jenkins /var/lib/jenkins -R
- restart jenkins
- use your jobs :D
According to the count of up-votes or comments, I could think the possibility of create a new plugin :)
Solution 16 - Jenkins
Simple php script worked for me.
Export:
// add all job codes in the array
$jobs = array("job1", "job2", "job3");
foreach ($jobs as $value)
{
fwrite(STDOUT, $value. " \n") or die("Unable to open file!");
$path = "http://server1:8080/jenkins/job/".$value."/config.xml";
$myfile = fopen($value.".xml", "w");
fwrite($myfile, file_get_contents($path));
fclose($myfile);
}
Import:
<?php
// add all job codes in the array
$jobs = array("job1", "job2", "job3");
foreach ($arr as $value)
{
fwrite(STDOUT, $value. " \n") or die("Unable to open file!");
$cmd = "java -jar jenkins-cli.jar -s http://server2:8080/jenkins/ create-job ".$value." < ".$value.".xml";
echo exec($cmd);
}
Solution 17 - Jenkins
This does not work for existing jobs, however there is Jenkins job builder.
This allows one to keep job definitions in yaml files and in a git repo which is very portable.
Solution 18 - Jenkins
Importing Jobs Manually: Alternate way
Upload the Jobs on to Git (Version Control) Basically upload config.xml of the Job.
If Linux Servers:
cd /var/lib/jenkins/jobs/<Job name>
Download the config.xml from Git
Restart the Jenkins
Solution 19 - Jenkins
As a web user, you can export by going to Job Config History, then exporting XML.
I'm in the situation of not having access to the machine Jenkins is running on and wanted to export as a backup.
As for importing the xml as a web user, I'd still like to know.
