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
• Run build tool task
• Compile your project
• Support annotaion processor
• Analyze java source (hooks into build)
• Code completion
• Optimize import
• Jump declaration (without source)
• Run junit test (include test runner)
• Search references
• Full-featured text search (default off)

Meghanada-Server support only emacs client (meghanada-mode)

The Meghanada architecture is almost the same as ensime. It is client server model.

Meghanada updates any information when saving and compile the java file.
