When you import a project (using m2e's import wizard, not the default Eclipse wizard) you should be shown a screen with parts of the build that m2e-core doesn't know how to handle. At this point it should suggest you install connectors such as m2e-wtp, these help configure Eclipse for unknown Maven plugins (with later versions of m2e the plugins themselves can include metadata).
Make sure you didn't choose to ignore the maven plugins (such as war) and check your pom for error markers.
