Javalens MCP Overview

JavaLens provides semantic analysis for Java codebases through Eclipse JDT, including symbol navigation, reference searches, call hierarchies, refactoring, and code metrics. Use it when text search or basic language-server navigation cannot reliably resolve inheritance, overloads, generics, or access types. It supports Java source from versions 1.1 through 25 and requires Java 21 or later to run.
