Formerly known as the Workflow plugin. Originally inspired by the discontinued Build Flow Plugin.

Plugins that implement Pipeline steps or integrate with Pipeline-related APIs should not depend on workflow-aggregator because it includes many unncessary dependencies. Instead, they should depend only on the plugins that provide the APIs necessary for the integration. For the common case of implementing a Pipeline step, plugins typically only need to depend on workflow-step-api. In order to test Pipeline-related functionality, plugins need test-scope dependencies on workflow-job and workflow-cps. Additional test-scope dependencies on plugins like workflow-durable-task-step or workflow-basic-steps may be needed for more complex tests.
