Configure seed jobs

Requires job-dsl >= 1.74

As explained in seed-jobs.md, jobs declaration is useful to create an initial set of jobs.

For now, it is using the job-dsl-plugin so this plugin needs to be installed on your Jenkins instance for this sample to work.

The Job DSL plugin uses groovy syntax for its job configuration DSL, so a mix of YAML and groovy must be used within the configuration-as-code file.

sample configurations

bitbucket.yaml file is an example of a configuration file with Jenkins and an Organization Folder Job Type with automatic branch discovering in Bitbucket. It requires Branch API plugin and Bitbucket Branch Source plugin to be able to run this demo. $BITBUCKET_URL is a system environment variable that needs to be defined before Jenkins is started.

pipeline.yaml file is an example of configuring a folder and a declarative pipeline job within that folder.

multibranch-github.yaml file is an example of a multibranch pipeline job configured with GitHub as branch source, an orphaned item strategy and periodic scan triggers of 5 mins.

implementation note

The main issue with the jobs declaration for now is the difference in the Traits declaration due to JENKINS-45504. When is is resolved, the workaround using the configure part will no longer be needed and all traits will be declared under the organizations section.

Job DSL only allows periodic(int min) for configuring a trigger for now. So to configure "1 day" for example, we need to use the configure workaround as shown in bitbucket.yaml
