How to use emacs as my JAVA IDE?

Question

I would like to use emacs instead of Netbeans which gets too bloated on my computer. I already have JDEE, I did not dig it, but it looks like it lacks:

• Classes testing : run a class which has a main method, but which is not the main class of the project
• Maven integration : this is a minor wish as Netbeans doesn't support maven that well too.

Answer 1

I recommend you to use malabar-mode instead of JDEE - malabar is the only modern mode for Java development currently available for Emacs. It offers:

• Tight integration with Maven

• A Groovy console for rapid prototyping and exploratory programming

• JUnit integration, both for running tests standalone and through Maven

• Import help; import one class or all needed classes in the buffer (with prompting if the class name is ambiguous)

• Extend class / implement interface / override method helpers

• Simplistic refactorings
