This is how it's supposed to work. During 'install' or 'deploy' pom
is just copied to repository. And it's a maven-release-plugin task
to modify pom during release process so there's a change in
version of artifact.
mvn help:effective-pom provides you how maven interpret your
pom. Maybe there should be a (I think that a very dangerous)
property that will allow maven to 'install/deploy' serialized version
of 'effective pom' instead of just copy project pom with
non-interpolated properties?
