Brian Fox closed MENFORCER-11.
------------------------------

       Resolution: Fixed
    Fix Version/s: 1.0

Enforce-once has the @aggregator removed and is now deprecated.

Unfortunately, in Maven, the @aggregator only applies to command line invocation and has no real effect when bound to a pom (at least not the run once desired effect).

In the future, I may add caching to the rules to allow things to run once, but the plugin will still execute for all children. A rule will need to declare if it is safe to cache or not.

> In 1.0-alpha-3, the enforce goal now requires dependency resolution to support the new dependency rules (noSnapshots, noBannedDependencies). Because enforce-once extends and adds as an aggregator, this causes the maven bug MNG-2277 to appear. The work around for now is to use enforce not the enforce-once goal (the aggregator part of enforce-once doesn't work anyway).
> The fix would be to resolve the dependencies manually in the plugin or to make a new mojo that requires dependency resolution and put enforce and enforce-once back the way they where.
