Basic Build Pipeline

A single-unit build pipeline. This is best used with the multibranch pipeline or a pipeline stored within the application code.

An alternate application of this pipeline would be to create separate build pipelines within the same repository. These could then be configured within the Jenkins Job to trigger simultaneously on all commits to the repository.

Build Units

This pipeline contains an example for building a single deployment unit and triggering a deployment if successful.

Post Job

On success, this job will trigger a 'Continuous Deploy' pipeline into the first environment.

Scripts

This example uses groovy scripts from the jenkins-shared-library

Example
