## What it is
Project Lombok is a Java library that plugs into compilers (javac, ECJ) and build tools to automatically generate boilerplate code like getters, setters, equals, hashCode, toString, builders, and logging fields via annotations. It also integrates with IDEs such as Eclipse, IntelliJ IDEA, NetBeans, and VS Code so the generated code is visible during editing.

## Use cases
- stop writing getters and setters in java classes
- generate equals and hashCode automatically
- add a builder pattern to a java class with one annotation
- reduce boilerplate in java data classes
- auto-generate constructors in java
- automate logger variable declarations in java
- make immutable java classes easily

## When to choose
- you write Java and want to eliminate repetitive boilerplate like getters, setters, and builders
- you want annotation-driven code generation that works with Maven, Gradle, and major IDEs
- you maintain large Java codebases where reducing boilerplate improves readability

## When to avoid
- your team dislikes annotation-based 'magic' and prefers explicit code or Java records
- you work in a non-JVM language
- you need features with guaranteed long-term support and dislike compiler-modifying tools
