Maven build complains about 'no module descriptor'

[eeverman]

This is a good first task on the AndHow project if you know Maven well

The Maven build inserts some warnings about missing module descriptors. Can these be addressed or quieted? The build does work as expected.

no module descriptor for org.yarnandtail:andhow 
no module descriptor for org.yarnandtail:andhow-core
no module descriptor for org.yarnandtail:andhow-annotation-processor

Perhaps I could try this as well, @eeverman ?

Addressed by #449

This error can be eliminated by moving to Java 9+ and leveraging its modular build system as suggested here by @rfscholte

As a bonus, a couple of other errors with com.sun:tools are eliminated as well.

Apparently the module issues will not go away until we move to idk 9, so I am moving this issue to the 0.6.0 milestone.
