Hi Wayne,
The app version is '1.0-SNAPSHOT'.
The Maven is:
$ mvn --version
Apache Maven 3.0.3 (r1075438; 2011-02-28 19:31:09+0200)
Maven home: /opt/maven
Java version: 1.6.0_29, vendor: Sun Microsystems Inc.
Java home: /opt/jdk1.6.0_29/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.2.0-25-generic", arch: "amd64", family: "unix"
Below are the POMs which I use to reproduce the issue.
Directory structure:

Question:
Why Maven didn't complain on second build?
What are the versions of the various projects in your build?
