RePatch is a refactoring-aware patch integration tool for structurally divergent Java forks. It automates bug-fix transfer across related codebases even when standard cherry-pick fails because of method moves, renames, or broader structural reorganization.
{"RePatch begins from a familiar maintenance failure" => "a bug-fix commit exists in one variant but does not apply cleanly to another because the target has drifted structurally. Instead of giving up after a failed cherry-pick, RePatch detects refactorings, temporarily inverts them to restore alignment, applies the patch, and then replays the original transformations."}
The approach is designed for long-lived Java variants that continue evolving independently. The repository includes the core integration pipeline, data models for conflict and file analysis, a database layer for result tracking, and a reproducibility package with sample and full evaluation data.
