16. Does it make sense to manage jenkins with a build automation tool? Question (Think About It…)
17. Gradle Jenkins Plugin Concepts Gradle (static model) Templates Views Jobs Jenkins (live model) Views Jobs Updates

19. Gradle Jenkins Plugin jenkins { servers { … } templates { … } jobs { … } views { … } } Conventions
20. Servers servers { server1 { url ‘http://jenkins.somewhere.com’ username ‘user1’ password ‘password1’ } } Secured
21. Servers servers { server1 { url ‘http://jenkins.somewhere.com’ secure false } } Unsecured
22. Templates templates { template1 { xml file(‘template.xml’) } } XML
23. Templates templates { template1 { dsl file(‘template.dsl’) } } DSL
24. Jobs jobs { build_job1 { server servers.server1 definition { xml file(‘build_job1.xml’) } } } XML
25. Jobs jobs { build_job1 { server servers.server1 dsl { using ‘template1’ } } } DSL
26. Views views { view1 { xml file(‘view1.xml’) } } XML
27. Views views { view1 { dsl { … } } } DSL
28. Multiple DSL Form jenkins { defaultServer servers.server1 dsl fileTree(‘jenkins’).include(‘*.dsl’) dsl { … } }
