fj-doc-mode-poi, native-image configuration in groupId/artifactId subfolder #1

To avoid a situation when constituent parts of a project are built with overlapping configurations, we recommended you use subdirectories within META-INF/native-image: a JAR file built from multiple maven projects cannot suffer from overlapping native-image configurations. For example:

foo.jar has its configurations in META-INF/native-image/foo_groupID/foo_artifactID
bar.jar has its configurations in META-INF/native-image/bar_groupID/bar_artifactID

As described here :

and here :
