Extensions

The Seed plug-in defines several extension points.

Adding steps to the root seed job

The Docker image provided by the Seed plug-in has a predefined seed job, but in most of the cases, you'll define yourselves this seed job using a Project seed generator build step.

You are free to define any other additional step you need in this job, and/or to define several types of seed jobs.

Adding steps to the branch seed job

See the [pipeline extensions documentation](Pipeline extensions) to know how to have specific steps added to a branch seed job.

Adding steps to the project seed job

See the [project extensions documentation](Project extensions) to know how to have specific steps added to a project seed job.

Branch additional parameters

By default, the branch seed and the underlying branch pipeline generator are passed only the default Seed parameters, like BRANCH and SEED_BRANCH.

It is possible to allow for additional parameters which are entered at project seed level and then propagated at lower levels.

This is done at configuration level - by declaring branch-parameters at project, class or global level. Each parameter is a name and a description. Parameters will be entered as string parameters.

For example:

classes:
   - id: my-class
     branch-parameters:
        BRANCH_PARAM: Additional parameter

For a project using the my-class class, when its project seed job is fired, an additional parameter BRANCH_PARAM will be requested, on top of the Seed default BRANCH parameter.

This BRANCH_PARAM value will be available in the branch seed parameter and also in the pipeline script, like in seed/seed.groovy.

Branch SCM path

See [Branch SCM path](Branch SCM path).

connectors

By default, only GitHub WebHooks and HTTP connectors are supported, but custom ones can be added. See the connector documentation for more information.

Additional SCM support

To be implemented and documented. At the moment, only Git and Subversion are supported out of the box.
