Yeah, this configuration style is definitely a kludge around this Maven
shortcoming.
About submodules, though, you can see this in lucene/codecs/pom.xml.template
aggregation POM - this is how maven specifies submodules (rather than via
implicit recursive directories; submodules can be physically located in sibling
directories):
<modules>
<module>src/java</module>
<module>src/test</module>
</modules>
Probably should be a comment in each of the three pom.xml.template files for
each module: in the aggregation POM, the src/java POM and the src/test POM.
