The Hidden Pitfalls of Using Lombok in Java Projects

Lombok is a popular Java library that uses annotations such as @Getter, @Setter, @EqualsAndHashCode, and @ToString to automatically generate the repetitive boilerplate code found in typical JavaBeans. The article first shows a verbose class definition with explicit fields, getters, setters, equals, hashCode, and toString methods, then demonstrates how Lombok can shrink the same class to a few lines of annotations, and finally presents the even more compact @Data annotation that bundles all these features.

While Lombok makes the source code appear slimmer and more “stylish,” the author points out several drawbacks: (1) incompatibility with newer JDK versions (e.g., Java 11) requiring removal of Lombok annotations; (2) forced adoption of the Lombok plugin for anyone consuming the code; (3) loss of explicit method visibility, making the class harder to understand and debug; (4) increased coupling because every dependent module must also include Lombok; and (5) the overall risk of adding technical debt that outweighs the short‑term convenience.

The conclusion advises developers to weigh these trade‑offs carefully, suggesting alternatives such as Kotlin or Scala for more concise JVM code, and to discuss Lombok usage within the team before committing to it in large or long‑lived projects.
