There's nothing presumptive about the fact that it HAS been deprecated
in trunk for quite some time now. (since it was still called 2.1-snap)
The aggregator is full of problems and usually leads to recursive
builds when you bind it to the lifecycle. A complely new concept is
needed to handle this use case.

Hi Brett,
Hi,
I noticed that the 'aggregator' parameter for a MOJO is slated for
deprecation in a future release of Maven.

Seems presumptive on the part of the author. It has both its
usefulness and its problems, and it being superceded is likely to
be part of a greater revision of the lifecycle rather than a one-
off deprecation.
I agree. The @aggregator is certainly useful, and IMO the concept
could even be extended to allow a user to specify that a specific
goal should run as an aggregator.
ie it would be great if a user could specify in the plugin
configuration in the pom.xml that goal X should behave like an
aggregator, or at least specify that goal X should only get run a
single time at the executionRoot of the build. Does this make sense?
What should be used instead, to fulfill the following use-case:
- a multi-module project, which would like to assert something
about the entire project at the very end of the build.
A concrete example is mentioned on our Clover Forums at http://forums.atlassian.com/post!reply.jspa?messageID=257294857
.
The user would like to only run clover2:check on the entire
project, not on each sub-module.
@aggregator will work for your situation
The only other solution available today is to run the plugin from a
separate module that depends on all the others (this is typically
how dependency-based aggregation is really done in Maven).
Thanks for this work-around. I will mention that to the user.
Cheers,
Nick
