Top Eclipse plugins I wouldn't go without

Using an IDE to develop today is necessary but any IDE worth his salt can be enhanced with additional features. NetBeans, IntelliJ IDEA and Eclipse have this kind of mechanism. In this article, I will mention the plugins I couldn’t develop without in Eclipse and for each one advocate for it. m2eclipse Maven is my build tool of choice since about 2 years.

Ego Driven Architecture

Whoever is in charge of software architecture, be they senior developers, whole teams like in agile practice or architects-per-se, it is a deep trend to apply what I like to call Ego Driven Architecture (or EDA for short, not to be mistaken with Event Driven Architecture).
