Guiding principles

1. Make it valuable 2. Make it easy 3. Make it fast 4. Make it pretty and always [YAGNI](https://en.wikipedia.org/wiki/You_aren%27t_gonna_need_it), [DRY](https://en.wikipedia.org/wiki/Don%27t_repeat_yourself) and [KISS](https://en.wikipedia.org/wiki/KISS_principle)

So.. what's new?

We have contibuted to job-dsl project
Templates are gone
Why?

It was fragile and brittle solution
Replaced by Groovy builders
Why?

Solves our passing parameters problems

no "hard-coded" jobs

Less Jenkins pollution

Here is a simple example


                    ```

                    import jenkins.automation.utils.SiteMonitorJobBuilder

                    new SiteMonitorJobBuilder(
                        name: "my-site-pulse-check",
                        description: "Sample url pulse check job",
                        cronSchedule: "@daily",
                        urls: ["http://google.com","http://yourethemannowdog.ytmnd.com/"]
                    ).build(this);

                    ```

Slightly more involved example


                    ```

                    import jenkins.automation.utils.JsJobBuilder

                    String basePath = 'JsJobSamples'
                    List developers = ['irina.muchnik@cfpb.gov', 'daniel.davis@cfpb.gov']
                    def repos = [
                        [name: 'jenkins-automation', url:"https://github.com/cfpb/jenkins-automation@2.0"],
                        [name: 'collab', url: "https://github.com/cfpb/jenkins-automation"]
                    ]

                    folder(basePath)
                    {description 'This example shows how to create jobs using Job builders.'}

                    new JsJobBuilder(
                        name: "$basePath/MyProjectJavascriptJob",
                        description: 'An example using a job builder for a Javascript build jobs project.',
                        repos: repos,
                        emails:developers,
                        use_versions: true )git a
                    .build(this)

                    ```
