spring-boot-project-creator

This skill scaffolds a new Spring Boot project (3.x or 4.x) from scratch by downloading a base project from the Spring Initializr API and then generating a standardized package structure and configuration. It solves the boilerplate-heavy task of bootstrapping a backend service by walking the user through project parameters, letting them choose an architecture style, and wiring in data stores and local infrastructure so the result is a build-ready project.

The workflow gathers configuration through AskUserQuestion (group ID, artifact ID, package name, Spring Boot and Java versions, architecture, Docker services, and build tool) with sensible defaults, then uses curl to download the scaffold from start.spring.io with a base set of dependencies (web, validation, data-jpa, testcontainers) plus conditional ones for PostgreSQL, Redis, or MongoDB. It generates either a Layered (controller/service/repository/model) or DDD (domain/application/infrastructure/presentation) package layout, creates placeholder classes such as OpenAPI configuration, a global exception handler, and a standard error-response record, configures application.properties for the selected data stores, and sets up Docker Compose for local development.

It targets Java backend developers starting a new Spring Boot application, bootstrapping a microservice, or initializing a backend with JPA, SpringDoc OpenAPI, and containerized dependencies. Prerequisites include a JDK (17+, Java 21 recommended), Maven, Docker and Docker Compose, and curl/unzip. The skill declares Read, Write, Edit, Bash, Glob, Grep, and AskUserQuestion; its Bash usage centers on downloading the official Initializr archive and creating project files.
