Storing this information in POM sure looks ugly, but there are important 
reasons to do that:

1. POMs are shared across teams through Maven repositories and through 
SCMs. Eclipse settings are not.
m2e is supposed to generate a complete, working eclipse project 
configuration no matter where you pull the project from. The resulting 
dotfiles (.project, .classpath, .settings/*) are transient and workspace 
specific. Sharing the across the team through SCM is _not_ recommended 
because it does more harm than good.

2. POMs are inherited. If the lifecycle mapping is placed outside of 
POM, either you need to do set it for each and every module separately, 
which is clearly unacceptable, or implement a mechanism of sharing and 
inheritance of these settings between module parallel to what is already 
done with POMs. This is not a workable solution either.

If you can't live with having this information in the POM, you need to 
create an eclipse plugin that will provide lifecycle mapping for the 
plugins that your project / company uses. Everyone in your team needs to 
install it, or get it preinstalled in their Eclipse when they start 
working on a project, and everything will be fine. All the scary error 
markers will go away :)
