Translate Jenkins XML jobs to YAML. The YAML can then be fed into Jenkins Job Builder.

Have a lot of Jenkins jobs that were crafted by hand over the years? This tool allows you to convert your Jenkins jobs to JJB quickly and accurately.


You can install a released version from PyPI::

 pip install jenkins-job-wrecker

Or, if you want to hack on it, install it directly from GitHub::

 virtualenv venv
 . venv/bin/activate
 git clone
 python develop

You will now have a jjwrecker utility in your $PATH.


Let's say you have an XML definition file for "my-job". You'll typically find these .xml files on your Jenkins master, maybe in /var/lib/jenkins/jobs/. Here's how you convert that job file to YAML::

 jjwrecker -f path/to/my-job/config.xml -n 'my-job'

This will write my-job.yml in a directory named "output" in your current working directory. You can then commit my-job.yml into your source control and use JJB to manage the Jenkins job onward.

In addition to operating on static XML files, jjwrecker also supports querying a live Jenkins server dynamically for a given job::

 jjwrecker -s -n 'my-job'

It will write output/my-job.yml as above.

To make jjwrecker translate every job on the server, don't specify any job name::

 jjwrecker -s

jjwrecker will iterate through all the jobs and create .yml files in output/.

If your Jenkins instance requires a username and password to connect to the remote Jenkins server, you can set these as environment variables, exported before hand or right before running the CLI tool::

 JJW_USERNAME=alfredo JJW_PASSWORD=go-tamaulipas jjwrecker -s

If you receive the error Don't know how to handle a non-empty <actions> element., you have actions in your xml for that job (probably from plugins). If you know that you don't need this information in your JJB yml job config, try the -a flag.

If your Jenkins instance is using HTTPS and protected by a custom CA, add the CA's public cert to your system certificate store:

  • Fedora: /etc/pki/tls/certs directory,
  • Ubuntu: /usr/local/share/ca-certificates/

After you've placed the PEM-formatted file there, run c_reshash in that directory to create the CA certificate hash symlink. jjwrecker uses python-jenkins, which in turn uses six's urllib, and that library will validate HTTPS connections based on this openssl-hashed directory of certificates.
