Emacs Java Malabar Mode
I have used JDEE for my java projects in Emacs. JDEE doesn't work well for maven. I recently came across Malabar mode which has better support for Java Maven projects in Emacs.
I was able to install malbar-mode using melpa in Mx list packages. But when I get an error mvn package
for my simple app https://github.com/vijayendra/JavaSrc/tree/master/my-app
Projects.get('/home/egnyte/src/my-app/pom.xml', []).run(['package'], [], [:])

How can I get malabar mode to work?
source to share
There are two answers.
Firstly malabar mode gets stuck in maven 3.0.4, so try this version. Also don't install lib directory. It should be installed automatically.
Secondly, to get around the maven version, I am rewriting malabar mode from scratch. Follow the instructions at https://github.com/m0smith/malabar-mode/blob/develop/doc/2.0/INSTALL.md . This version should work for all maven versions after 3.0.4. This is a work in progress and not all features are still there.
If you have any problems or suggestions, please post an issue in the GitHub repo, as now is the right time to find out your wishes.
EDIT: 2.0 malabara released in MELPA. To install now:
``,
(load-file "~/projects/cedet/cedet-devel-load.el")
(add-hook 'after-init-hook (lambda ()
(message "activate-malabar-mode")
(activate-malabar-mode)))
(add-hook 'malabar-java-mode-hook 'flycheck-mode)
(add-hook 'malabar-groovy-mode-hook 'flycheck-mode)
