Question

I am an eclipse power and who has ignored maven due to the historically poor maven / eclipse integration. m2e seems to be maturing and I am taking it out for a serious test drive.

I want to understand how m2e works within eclipse, so I can better get the two working smoothly together and to understand the still cryptic error messages and problems that arise.

I have tried googling for an explanation of the m2e eclipse integration architecture and found nothing that provides a good account of how the integration works. rather just a lot of scattered blog posts all over the web.

Can anyone provide a solid overview of how m2e bridges the gap between the eclipse view of the world and maven view of the world? Especially how does maven integrate into the incremental builds that eclipse does? What is the impact on eclipse stability / performance from using m2e.

I have found the details I was looking for in a Presentation from Eclipse Con titled “m2e, an exercise in mixing oil and water”

http://www.eclipsecon.org/europe2012/sites/eclipsecon.org.europe2012/files/EclipseConEU2012-m2e-talk.pdf

Abstract:

m2e is a popular Eclipse IDE plugin with stated project goal “to
provide a first-class Apache Maven support in the Eclipse IDE”. In
this talk I will give an overview of Maven/Eclipse integration
approach implemented by m2e, highlight differences between Maven and
Eclipse that make proper integration difficult or impossible and will
discuss possible ways to improve the integration. The talk is targeted
at Eclipse and Maven developers who want to better understand
challenges of Maven/Eclipse integration and advanced m2e users who
want to know what happens “under the hood”.
