when you invoke a phase, maven invokes all the phases, in the lifecycle to which the phase belongs, up to and including the phase you specified

you are invoking the clean phase, which is part of the clean lifecycle, so maven will invoke all the mojos attached to the pre- clean phase, and then all those attached to the clean phase, and then it will stop

the same confusion happens with integration tests... where people think they should dunn them with "mvn integration-test" but this is not the way they should work. the integration-test phase should run all the tests and *never fail the build*. then a plugin attached to the verify phase should check the results of the integration tests and fail the build if necessary. with that case you invoke the integration tests with "mvn verify". this allows a IT test container to be started and stopped in the pre-it and post-it phases

My understanding of the maven clean lifecycle is that the following phases
will be run in order when you perform a "mvn clean"

       pre-clean
       clean
       post-clean

And with the ant plugin you can run code in any of these phases.

The issue is that the post-clean does not seem to work. Am I missing something?

Here is a simple pom which does an ant echo task in each phase.

When I run "mvn clean", the post-clean is never echoed.
