A plugin that gives an AI agent access to the Eclipse JDT.LS Java language server, so the agent can navigate, complete and diagnose Java code.

What does the agent get from it?

Java code intelligence: navigation, completions and diagnostics supplied through the language server.

Does it work with languages other than Java?

It is built around the Java language server, so it is intended for Java code.
