Description

This was originally reported against as https://issues.sonatype.org/browse/TYCHO-531. When the same pom.xml file is referenced from multiple <module/> element, the build fails with rather unhelpful error message like

[ERROR] Two or more projects in the reactor have the same identifier, please make sure that <groupId>:<artifactId>:<version> is unique for each project: {org.jboss.tools.build:org.jboss.tools.build.libs:1.0.0-SNAPSHOT=[/qa/hudson_ws/workspace/jbosstools-3.2.0.Beta2.tests/sources/build/libs/pom.xml, /qa/hudson_ws/workspace/jbosstools-3.2.0.Beta2.tests/sources/build/libs/pom.xml]}

To help user troubleshoot the problem, we need to provide pom.xml and ideally line numbers that reference the same module.
