eclim server

http://eclim.org/install.html

had to manually symlink eclim in home/alx/eclipse/java-oxygen/eclipse after install. use the eclimd symlink there as a guide.

set up gradle project in eclipse

• install Buildship eclipse plugin
• import Gradle project in eclipse

start eclim

start with:

/home/alx/eclipse/java-oxygen/eclipse/eclimd

then M-x eclim-mode in a java buffer.

when dependencies change

• close eclim
• start eclipse
• File -> Gradle ->

meghanda mode

https://github.com/mopemope/meghanada-emacs

(require 'meghanada) (add-hook 'java-mode-hook (lambda () (meghanada-mode t) (flycheck-mode +1)))

shadow jar (uberjar)

http://imperceptiblethoughts.com/shadow/

adds shadowJar gradle task.
