Today I noticed that the "jacoco.exec" file was now in the Parent's "target"
directory, so I changed each of my references to "jacoco.exec" to point to it.
Then when I ran "mvn clean install -P create-jacoco-reports" and noted that it
declared a successful build, it did generate a "jacoco.xml" file, but the tiny
one again, with just contents:
<?xml version="1.0" encoding="UTF-8" standalone="true"?>
<DOCTYPE report SYSTEM "report.dtd" PUBLIC "-//JACOCO/DTD Report 1.0//EN">
<report name="Parent">
<sessioninfo dump="1389289493869" start="1389289427703"
id="A-1007000-72927de2"/>
</report>
I'm also still getting several cases where the Maven output says, "Skipping
JaCoCo for project with packaging type 'pom'", it's still complaining,
"Skipping JaCoCo execution due to missing execution data file", and in the TESTS
section I'm still getting:

Can anyone tell me why this is happening, and what I need to do to get JaCoCo
to calculate my Child component's code coverage?
