Gradle Show and Tell
The document is a presentation by Steve Pember discussing the use of Gradle for building software, emphasizing topics like continuous integration, deployment strategies, and the roles of Gradle and Jenkins in the build process. It highlights the benefits of Gradle over Maven, such as performance and task graph management, while also addressing the need for quality checks and structured build planning. Key takeaways include the use of a parent build plugin for project management and the implementation of quality gate checks on every code push.

- 41. Local Vs RemoteBuilds
- 42. @svpember Local Vs RemoteBuilds • Local: Fast, with some minimum level of acceptable testing • Remote: thorough testing, with some minimal acceptable build time (15 min?) • Your Gradle file will be more expressive than local needs • Needs to support both Local and Remote in one build
- 43. @svpember Parent vs ServiceBuild File • Parent: defines global config • Parent: defines approved dependency versions, with excludes • Service: local overrides
- 44. @svpember Our (MY) Requirements: •No building ‘final’ artifact from command line • No deploying from command line • Should act as guardrails for additional services and new engineers
