Stop Claude Code Interface Blindness: Hook Eclipse JDT LS via MCP for AST-Aware Java Refactoring
Claude Code is a beast in the terminal, but letting it raw-grep your enterprise Spring Boot codebase is a recipe for hallucinated method signatures and broken builds. If your AI agent doesn't understand the Abstract Syntax Tree (AST) of your decoupled interfaces, it is simply guessing.
Why Most Developers Get This Wrong
Relying on grep-based search: Claude Code's default file search tools treat Java like raw text, completely missing runtime polymorphism and complex @Qualifier annotations.
Ignoring the Model Context Protocol (MCP): Developers waste massive amounts of context window tokens pasting entire classes instead of letting Claude query a local language server.
