Job DSL1.58Minimum Jenkins requirement: 1.651ID: job-dsl
Last released: 7 days ago
The job-dsl-plugin allows the programmatic creation of projects using a DSL. Pushing job creation into a script allows you to automate and standardize your Jenkins installation, unlike anything possible before.
Jenkins is a wonderful system for managing builds, and people love using its UI to configure jobs. Unfortunately, as the number of jobs grows, maintaining them becomes tedious, and the paradigm of using a UI falls apart. Additionally, the common pattern in this situation is to copy jobs to create new ones, these "children" have a habit of diverging from their original "template" and consequently it becomes difficult to maintain consistency between these jobs.
The Jenkins job-dsl-plugin attempts to solve this problem by allowing jobs to be defined with the absolute minimum necessary in a programmatic form, with the help of templates that are synced with the generated jobs. The goal is for your project to be able to define all the jobs they want to be related to their project, declaring their intent for the jobs, leaving the common stuff up to a template that were defined earlier or hidden behind the DSL.

After installing the plugin, you'll get a new Build Step entry named "Process Job DSLs". Type the DSL directly in the text box, or point to a file in the workspace.
The DSL allows the definition of a job, and then offers a useful set of functions to configure common Jenkins items. A configure is available to give direct access to the config.xml before generating the job. The script is groovy code, which can be very powerful. Here's an example to create a job for each branch in a git repo:
- DSL - Scriptable via Groovy
- DSL - Direct control of XML, so that anything possible in a config.xml is possible via the DSL
- DSL - Helper methods for common job configurations, e.g. scm, triggers, build steps
- Plugin - DSL can be put directly in a job
- Plugin - DSL can be put into SCM and polled using standard SCM triggering
- Plugin - Multiple DSLs can be referenced at a time
- Plugin - Tracks Templates used, will update derivative jobs when template is changed
See the wiki for specific steps and other examples.
- Create your set of Jenkins jobs which will serve as the templates (It is a good idea to use a naming convention for these jobs which clearly indicates that these are templates)
- Create a Jenkins Job using the Free-style project style to run your DSL Scripts. This is called a "Seed" job.
- Configure the seed job, by adding a "Build Step" of type "Process Job DSLs" and paste in the body of the DSL.
- Run the seed to generate your new jobs from your script. When successful, and the "build result" page will list the jobs which have been successfully created.
- Finally, it is good practice to organise your Jenkins UI with some new tabs so that the management and template jobs are not the first thing a user sees when they login
