The sample pom.xml on SmartBear's website does not parse with Maven 3.3.9 or 3.0.1

The tags <phase>, <goal> and <configuration> are all flagged as unrecognized, causing a fatal error and the build to not run.

I have been told 3.3.9 is the most recent version of Maven. The sample pom.xml given on SmartBear's website does not run under it.
