Issue

We are in process of taking backup of all existing jobs and we want to convert all existing jenkins jobs to DSL Script to save them in SCM…
Is there a way we can convert all existing jenkins jobs to DSL Script?

Environment

If you just want to backup the Jenkins Job configuration, you can use the SCM Sync configuration plugin (https://wiki.jenkins-ci.org/display/JENKINS/SCM+Sync+configuration+plugin). It automatically commits every job modification to a SCM.

For DSL scripting, there is either:

JobDSL plugin: a Groovy DSL to create and configure job programmatically. JobDSL scripts can be stored in a SCM and job reconfiguration can even be triggered on commit on this repository. The plugin has a extensive documentation (https://wiki.jenkins-ci.org/display/JENKINS/Job+DSL+Plugin). It can be difficult to start with but it’s very powerful.
Literate plugin: a plugin using a file in the project source to explain on how to build the project. Documentation is here: (https://wiki.jenkins-ci.org/display/JENKINS/Literate+Plugin)

Unfortunately, none of theses plugins can automatically convert existing job configuration to a script. The YAML Project Plugin (https://wiki.jenkins-ci.org/display/JENKINS/YAML+Project+Plugin) can do that but the plugin is at its early stage.
