ddd4j-boot Version Selection

Overview

Spring Boot version and JDK are the entry points; the output is the complete Boot→ddd4j→JDK→Maven/POM tuple.

When to Use

• Choosing the ddd4j-boot maintenance line for a new project, given the Spring Boot version and JDK the organization supports.
• Planning an upgrade that crosses ddd4j main lines (for example Boot 2.7.x / ddd4j 1.0.x to Boot 3.5.x / ddd4j 2.0.x).
• Auditing whether an existing project's Boot→ddd4j→JDK→Maven/POM tuple is internally consistent.
• Deciding whether Boot 4.0–4.1 targets are buildable with the current Maven toolchain (Maven 4 / POM 4.1 required).
• Proving that the selected line's artifacts are remotely consumable from the private repository, not just present in a local cache.
• Explaining why a proposed parent/BOM combination is incompatible with the current JDK or Maven model.
