> @gnodet My first class of usecases is a consistent location for project
level settings ( https://issues.apache.org/jira/browse/MNG-5659 ) which will
solve a lot of practical problems for many of the projects where I work.
We need to split between _build settings_, and _project resources_ I think.
By _build settings_, I mean things that are loaded once for a given maven
session. Per-project `settings.xml` would be one of those.
However, locating _project specific resources_ is different, especially you
want to refer to the project root on the filesystem to let maven translate that
into an absolute path. I'm thinking about checkstyle rules referred to as
`build/checkstyles.xml` or similar.
When such projects are aggregated into a bigger project, the _build
settings_ can't really be loaded per-project. However, _project resources)
have to keep working.

> This is a request to expose a property *maven.multiModuleProjectDirectory*
> which is currently internal (or introduce a brand new one with analogous
> functionality).
> * For a single-module project, its value should be same as *project.basedir*
> * For multi-module project, its value should point to a project.basedir of a
> root module
> Example:
> multi-module // located at /home/me/sources
> +- module-a
> +- module B
> Sample multi-module/pom.xml:
> {{<project>}}
> {{ <parent>}}
> {{ <groupId>com.acme</groupId>}}
> {{ <artifactId>corp-parent</artifactId>}}
> {{ <version>1.0.0-RELEASE</version>}}
> {{ </parent>}}
> {{ <groupId>com.acme</groupId>}}
> {{ <artifactId>multi-module</artifactId>}}
> {{ <version>0.5.2-SNAPSHOT</version>}}
> {{ <modules>}}
> {{ <module>module-a</module>}}
> {{ <module>module-b</module>}}
> {{ </modules>}}
> {{</project>}}
> The property requested should return /home/me/sources/multi-module,
> regardless of whether it's referenced in any of the child modules (module-a,
> module-b) or in multi-module.
> Note that multi-module itself has parent (e.g. installed in a local
> repository), so the new property should be smart enough to detect it and
> still point to /home/me/sources/multi-module instead of the local repository
> where the corp-parent is installed.
> The use-case for such a property could be to have a directory for combined
> report of static analysis tools. Typical example - jacoco combined coverage
> reports.
