## What it is
A Neovim plugin providing extensions for the built-in LSP client to work with the Eclipse JDT Language Server for Java. It adds Java-specific refactoring, code generation, bytecode inspection, and debugger integration on top of Neovim's LSP support.

## Use cases
- set up Java language server support in Neovim
- refactor Java code from the terminal editor
- organize imports and extract methods in Java with Neovim
- debug Java applications inside Neovim
- generate constructors, toString, and equals/hashCode in Java
- view Java bytecode and memory layout without leaving the editor

## When to choose
- you develop Java in Neovim and prefer configuration as code
- you want eclipse.jdt.ls features like refactoring and DAP debugging in a terminal editor
- you use Maven or Gradle and are comfortable with Lua configuration

## When to avoid
- you want a GUI IDE experience with zero configuration - use IntelliJ IDEA or Eclipse
- you don't use Neovim
- you want out-of-the-box ease of use - the README explicitly targets experienced users

## Facets
- artifact type: plugin
