How to create a Job automatically using Seed Jenkins plugin and Job DSL script

How it works ?

Create a Freestyle Job called Seed Job and define the Job DSL script.

In the Seed JOb use the Process Job DSLs step to execute the Job DSL script to create a required job with all necessary configurations.

Job DSL script can be defined in two ways:

• Directly hardcoding in the Seed Job
• Store the Job DSL script in git repository and refer it in

Job DSL script is a groovy script which uses the Job DSL plugin to define the structure.

Job DSL script Reference:

• Official limited sub-set of the API reference
• Complete DSL API reference –> /plugin/job-dsl/api-viewer/index.html

Prerequisites

        stringParam('COMMIT', 'HEAD', 'Commit to build')

                branch "origin/master"
            }
            extensions {
                wipeOutWorkspace()
                localBranch master
            }
