When running the community test suite against the productized binaries, we get exceptions like this one:

testKieModuleUsingPOMMissingKBaseDefinition(org.kie.scanner.KieModuleBuilderTest)  Time elapsed: 0.175 sec  <<< ERROR!
java.lang.RuntimeException: org.apache.maven.project.ProjectBuildingException: Some problems were encountered while processing the POMs:

The problem here is that the code doesn't respect the "kie.maven.settings.custom" property, through which users can provide their own Maven settings file. Without this file, it is not possible for users to include additional repositories to look up artifacts in - and, therefore, the productized artifacts are not found.
