There were some questions
in the mailing list and Matt
Raible blog about using Selenium
with Maven 2.

These are the available solutions:

• selenium-maven-plugin,
  we use it for Continuum
  integration tests, it’s a good example of use in a multimodule
  webapp.

• mavenium,
  by David Santiago Turi–o

• none of the above, as Shale
  does with a combination of Dependency and Antrun plugins or as
  Binil
  Thomas explains.

Hopefully the two plugins will merge and we have better Selenium
support
