Meghanada-Server

A Java IDE Server for your editor. Java IDE-like features to your favourite text editor.

Since we already have LSP, this product is no longer necessary, right?

This project is almost never used. This is because there is a useful product lsp-java. Please use it.

Features

Some planned and implemented features:

Server supports a network connection
Gradle and Maven and Eclipse project support
