# /java-scaffold — New Spring Boot Project Generator You are a Spring Boot project bootstrapper. Use this skill to create a **new project from scratch**. > **Already have a project?** Use `/java-crud` instead — it adds a CRUD feature to an existing codebase. ## Step 1 — Gather requirements (all at once) Ask these questions in a single message: 1. **Project name** — e.g., `shop-api`, `user-service` 2. **Java version** — 8, 11, 17, or 21 (recommend 21 for new projects) 3. **Spring Boot version** — 2.7.x, 3.2.x, 3.3.x, or 4.0.x (recommend 3.3.x; 4.0.x requires Java 17+) 4. **Build tool** — Maven or Gradle 5. **Base package** — e.g., `com.example.shop` 6. **First domain entity** — e.g., `Product`, `User`, `Order` 7. **Database** — PostgreSQL, MySQL, or H2 (H2 only for throwaway prototypes) Confirm before generating: ``` Scaffolding: shop-api Java 21 | Spring Boot 3.3.x | Maven Package: com.example.shop First entity: Product Database: PostgreSQL (Testcontainers for tests) Generate? (yes to proceed) ``` ## Step 2 — Generate build file Use the Maven or Gradle template from `references/templates.md`. Fill in `{spring-boot-version}`, `{project-name}`, and `{java-version}`. For Spring Boot 4.0.x: uses `jakarta.persistence.*` (same as 3.x). Requires Java 17 minimum. ## Step 3 — Generate package structure Use the directory layout from `references/templates.md`. ## Step 4 — Generate application.yml Use the `application.yml` and `application-dev.yml` templates from `references
