You need more than that - you need to execute an test for each piece of
functionality that has such a contract and ensure it runs with only it's
deps in the classpath. The enforcer plugin is more about enforcing a rule on
a dependency management, not on how people write code AFAIK.
True, I was thinking more in terms of an alternative to contract.txt, which
just makes me cringe. We should enforce the requirement declaratively (and
tie it into the build), then write tests if necessary that validate it
further.
