[~michael-o], I guess you're looking for MNG-6118.

[~mkv22], you can give it a try by downloading a recent snapshot of Maven (4.0.0-alpha-1-SNAPSHOT) and seeing if you can get the desired behaviour on your sample project.

> I have a project consisting of an aggregator and a submodule, which inherits directly from the aggregator. I have the following scenarios:
>  * When I execute {{mvn clean site site:stage}} (without {{-pl .}}), the build is successful.
>  * When I leave out the extensions out of the {{pom.xml}}-file of my aggregator and execute the {{mvn -pl . clean site site:stage}}, the build is successful.
>  * When I put in extensions to the {{pom.xml}}-file of my aggregator but leave out the reports for {{index}} and {{modules}} (the only sites that refer to my submodule) by explicitly defining the report set in the {{pom.xml}}-file of the aggregator, the build is successful.
>  * As soon as I put extensions into the {{pom.xml}}-file of my aggregator and leave in the reports for {{index}} and {{modules}}, then execute the build {{mvn -pl . clean site site:stage}} for the aggregator, the build fails with a {{NullPointerException}}.
> I attached the error log of the last scenario and the {{pom.xml}} of the aggregator and its submodule to this ticket. This has never been a problem until the release of {{maven-project-info-reports-plugin 3.0.0}}.
> Hopefully I managed to understandably describe my issue.
