What problem does it solve?
You need a Spring Boot backend repo quickly but keep recreating the same Initializr choices and local Java/Docker checks by hand.
Who is it for?
Indie builders starting a Java API or SaaS backend who already use Docker locally.
Skip if: Kotlin-first stacks, serverless-only deploys without a JVM service, or teams forbidding curl downloads from external generators.
When should I use this skill?
User needs to create a Spring Boot Java project skeleton or asks to scaffold a JVM backend with the documented template.
What do I get? / Deliverables
You receive an unzipped Maven Spring Boot project with web, persistence, cache, validation, and Testcontainers wired for local Docker development.
- Unzipped Maven Spring Boot jar project directory
- starter.zip removed after extraction

How it compares
Use instead of ad-hoc Initializr clicks when you want repeatable curl-driven scaffolding inside the agent session.
