Overview
Kotlin JDSL is a Kotlin library for query building and execution. It uses ordinary Kotlin classes and built-in language features without requiring annotation processors or generated metamodels, targeting JPA/JPQL query workflows.

Key features
Build queries without generated metamodels or annotation processors
Existing Kotlin classes can be used directly so query expressions do not depend on generated model code.

Best fit
Before adoption
Version 3.9.0 adds Spring Boot 4 compatibility
The 3.9.0 release adds support for the Spring Data JPA Boot 4 proxy bean, so Spring Boot major upgrades should be checked against the matching integration version.
Sources: [2]
The README lists Java 8+ and Kotlin 1.7+ as user requirements
Those are the library's documented minimums, while the selected Spring and JPA stack may impose newer runtime requirements.
