svn commit: r497785 - /maven/plugins/trunk/maven-help-plugin/src/main/java/org/apache/maven/plugins/help/EffectivePomMojo.java

New Revision: 497785

URL: http://svn.apache.org/viewvc?view=rev&rev=497785
Log:
When help:effective-pom is called from within a pom,
only print out that pom's effective pom.
Added check to only dump all poms if the ${project} is the head of
the reactor list to enforce proper aggregator behaviour.

TODO: maybe this needs an update: find the current project
in the reactor projects, then dump that pom, and find all
modules recursively and dump those, so you can dump a sub-tree
of the reactor, when you run the mojo from the lifecycle.
