For future reference, if anybody else is in the situation I was in,
once solution is to package up your library with dependency classes
rolled up into the jar file.
The following added to the POM.xml under plugins accomplishes this:
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>attached</goal>
</goals>
</execution>
</executions>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</plugin>
