Description

This layer adds support for the Java language using the Eclim client/server.

Layer Installation

Layer

Add this layer to your ~/.spacemacs.

(setq-default dotspacemacs-configuration-layers '(java))

Eclim

Eclim provides the ability to access Eclipse features such as code completion, searching, code validation, and many more.

Installation

For installation check the official page.

Then set the Eclipse and Eclim paths in dotspacemacs/user-config, for instance:

(setq eclim-eclipse-dirs '("~/opt/eclipse")
                         '(eclim-executable "~/opt/eclipse/eclim"))

Usage

Currently you have to have eclimd already started. This layer doesn't try to control eclimd in no way although there's that option in emacs-eclim itself.
