cobol-modernization

End-to-end workflow for migrating COBOL codebases to Java.

Overview

This plugin orchestrates a multi-phase COBOL modernization project:

1. Build Setup — Configure compilation for both COBOL and Java, create test fixtures
2. Mainframe Planning — Document transformations needed to remove mainframe dependencies
3. Mainframe Removal — Convert CICS/VSAM code to standard COBOL
4. Java Migration — Translate standardized COBOL to idiomatic Java

Prerequisites

• GnuCOBOL compiler (cobc)
• Java 11+ with Maven or Gradle
• Python 3.13 with uv
• LLM API key (Anthropic or OpenAI)
