In this PR, we introduce a fallback for artifacts that only have a pom.xml file, without a jar file present. Multi-module projects often include "hollow" or "aggregator" modules. If these lack a physical JAR, AbstractNativeImageMojo.processArtifact() would throw an exception if the chosen maven phase was before the package phase. To mitigate this, we add a fallback that resolves the module's target/classes directory directly from the Maven Reactor.

This PR is based on a copilot-generated PR authored by @linghengqian (linghengqian#1), with minor cleanup and test changes.

Fixes: #727
