Spring Tools 5.4.0 Adds AI-Friendly Validations and Claude Code Support

The Spring Tools team has shipped version 5.4.0 of its IDE tooling suite, covering Visual Studio Code, Cursor, Eclipse, Theia, and now Claude Code. This release focuses on making it easier to adopt newer Spring idioms and improving the experience when working with AI coding assistants.

What's New

The headline feature is a set of new validations and quick fixes that help developers migrate to modern Spring annotations. The tooling can now suggest conversions to @ApplicationModuleListener, @SpringJUnitConfig, @RestController, and specific @Scope annotations. These are not just cosmetic changes; they align your code with current best practices and can simplify your configuration.

For those using Claude Code, the plugin can now render a project's logical structure, making it easier for the AI to understand the architecture and provide more relevant suggestions.

Performance and Stability

The release also includes significant speedups for various quick fixes and for repository-based version validation. Indexing source code has been made more reliable, which should reduce frustrating hangs and stale results.

The Eclipse distribution has been updated to the latest Eclipse 2026-09 release, bringing in all the upstream improvements.

Availability

Downloads are available from the Spring Tools page. The next release, 5.5.0, is scheduled for mid-December 2026.
