Re: [m2e-users] maven web apps not loading in Eclipse with M2E

[Guillaume Polet <guillaume.polet@xxxxxxxxx>]

Hi Steve,

I don't know about Webby but I have used m2e (and previously M2Eclipse) 
with the WTP-integration and as you said, it was kind of struggle to get 
things to work. However, I have noticed a great improvement in usability 
since Eclipse 3.7 for m2e and WTP integration. Honestly I was surprised 
(in a good way) of how simple it was to get it to work. You check out 
your project and you automatically get a project set up with the correct 
facets. If you modify your pom.xml in a way that this should be reflect 
in your project facets or deployment descriptor, just use the "Update 
project configuration" and you should be good to go (I have tested this, 
e.g., with the compiler target level, with the final name of the war, 
and some other stuffs and it worked like a charm).

Congratulations to the developers.

Guillaume
