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.
