I thought I'd post one last comment about this. For a brief period I was under the impression that fixing my dependencies somehow fixed this problem. That was not the case.
It appears the root cause was that in Eclipse I configured the installed JRE for Java 1.8. Since I have several versions of the Java JDK installed I simply changed my JAVA_HOME environment variable to point to the 1.7 JDK and then changed my installed JRE in Eclipse to also point to JDK 1.7. problem solved! I assume the Maven plug-ins for Eclipse (at least the version I'm using, 1.5.1) require Java 1.7!!! It would be great if someone would confirm this.
