# Java Decompiler Plugin

A Claude Code plugin for decompiling Java .class files and analyzing compiled Java projects.

## Features

- **Batch Decompilation**: Convert .class files back to Java source using CFR decompiler
- **Project Structure Analysis**: Analyze package hierarchy, dependencies, and architecture
- **Maven/Gradle Generation**: Generate build configuration files
- **Dependency Analysis**: Map class dependencies and JAR requirements
- **Code Understanding**: AI-assisted analysis of decompiled code

## Quick Start

### Prerequisites

1. Java 8+ installed
2. Download CFR decompiler:
   ```bash
   # Download CFR jar to scripts directory
   curl -L -o scripts/cfr.jar https://github.com/leibnitz27/cfr/releases/download/0.152/cfr-0.152.jar
   ```

### Usage

#### Decompile a project
```
/decompile-classes ./path/to/classes
```

#### Analyze project structure
```
/analyze-structure ./path/to/project
```

#### Generate Maven project
```
/generate-project ./path/to/decompiled
```

#### Analyze dependencies
```
/analyze-dependencies ./path/to/classes
```
