Michael Osipov commented on MPIR-400:
-------------------------------------
First of all, the child module is missing a relative path for the parent.
Otherwise it suffers from a chicken and egg problem.
This is a bug in Maven 3.6.3. See here:

[~martinkanters], [~mthmulders], any idea which JIRA issue in Maven might have
fixed this?
> mvn -pl . clean site site:stage fails when extensions are part of pom.xml
> -------------------------------------------------------------------------
>
> Key: MPIR-400
> URL: https://issues.apache.org/jira/browse/MPIR-400
> Project: Maven Project Info Reports Plugin
> Issue Type: Bug
> Components: index, modules
> Affects Versions: 3.0.0, 3.1.0, 3.1.1
> Environment: Apache Maven Version: 3.6.3
> Java version: 1.8.0_251, vendor: Oracle Corporation, runtime: C:\Program
> Files\Java\jdk1.8.0_251\jre
> OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows"
> Reporter: Marwa Khabbaz
> Priority: Major
> Fix For: waiting-for-feedback
>
> Attachments: error_log.txt, example.zip, pom_aggregator.xml,
> pom_sub-module.xml
>
>
> 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.
