Can it help with the Spring Boot 4 migration?

Absolutely. It identifies breaking changes such as the Jackson 3 namespace shift and @MockBean deprecation, providing specific code fixes for a smoother upgrade.

Does this skill support both Maven and Gradle?

Yes, it automatically detects and analyzes pom.xml for Maven and build.gradle files for Gradle projects to extract version and dependency data.

What Java version does it require?

The skill checks that your project is using at least Java 17, which is the minimum requirement for Spring Boot 4.x, and flags older versions as errors.

Does it check Spring Security configurations?

Yes, it specifically validates Security 7 requirements, including the removal of .and() chaining and the mandatory transition to Lambda DSL closures.

개발자 도구

Analyzes Spring Boot projects to ensure dependency compatibility, configuration correctness, and migration readiness for version 4.x.

소개

The Spring Boot Verify skill is a specialized diagnostic tool for Claude Code designed to audit Java projects for Spring Boot 4.x compatibility. It automatically identifies outdated dependencies, detects deprecated configuration patterns like legacy Security DSLs or Jackson 2 namespaces, and provides actionable remediation code. By scanning build files and application properties, it helps developers navigate the complexities of framework upgrades and maintains high standards for modern Spring Boot development and security compliance.
