Use different Maven versions for running the current build and the integration tests

I'm currently faced with the problem that my build (appassembler-plugin) can be done via Maven 3.0.X and Maven 2.2.1 but not with Maven 2.0.11. But on the other hand the appassembler-plugin itself can be used in Maven 2.0.11 or be more accurate that i would like to test this via the integration tests.

So currently i don't see a possibility to run my build of the plugin via Maven 3.0.3 and let the integration-tests run with a different Maven version (or may be oversight something?)...for example with Maven 2.2.1 or Maven 2.0.11.
So it would be very handy to have the possibility to use a different Maven version for running inside the integration tests than for the build itself.
