From 85496c39f42cfe4d3bcfb6459f5b848436e440e1 Mon Sep 17 00:00:00 2001 From: Patrick Dawkins Date: Sat, 16 Aug 2025 11:01:37 -0400 Subject: [PATCH 1/6] Add Bazel dependency parsing support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements reusable Bazel parser that integrates with language-specific managers: - Core parser supports BUILD, MODULE.bazel, and WORKSPACE files - Smart Maven coordinate conversion (e.g., com_google_guava_guava -> com.google.guava:guava) - Integrated with Java manager following existing multi-build-tool pattern - Comprehensive test coverage for all parsing scenarios - Designed for future expansion to Python, Go, and other languages 🤖 Generated with [Claude Code](https://claude.ai/code)
