Description

It looks like Maven 3.2.1 introduced a regression. Installing
extension which provides workspace reader triggers MNG-5503.

Maven resolves artifacts from reactor, workspace, repositories (in
that order). In standard Maven distribution there is no workspace,
but Maven provides an extension point which allows extensions to
install workspace reader by providing a component with role
org.eclipse.aether.repository.WorkspaceReader and role hint ide.

Installing workspace reader extension in Maven 3.2.1 triggers a
regression - Maven fails to resolve artifacts produced by reactor
build (MNG-5503). Even though artifact is present in reactor Maven
queries workspace about it and if artifact is not found there it
continues with repositories. Expected behaviour is resolving artifact
from reactor.

Steps to reproduce this:

1) download and extract apache-maven-3.2.1-bin.tar.gz
2) download dummy-extension.tar.gz and build it with mvn package
3) download reproducer for MNG-5503 from: https://bugzilla.redhat.com/attachment.cgi?id=784786
4) try to build reproducer project, it succeeds
5) copy dummy-extension-1.0.0.jar to Maven lib/ext
6) try to build reproducer project, it fails

When repeating the same steps for Maven 3.1.1 failure is not reproducible.
