-------------------------------------
Any Progress on this? Does *Fix Version/s:* [Issues to be reviewed for
4.x|https://issues.apache.org/jira/issues/?jql=project+%3D+MNG+AND+fixVersion+%3D+%22Issues+to+be+reviewed+for+4.x%22]
mean that it will be in 4.0 Release?
Both properties seems to be adequate
{*}maven.multiModuleProjectDirectory{*} and *{{project.topdir}}*
After reading
[https://maven.apache.org/guides/mini/guide-multiple-modules-4.html] and if you
just wand to have it in reactor builds i would use
*project.reactor.dir*
But the discussion about the naming is not so important. its more importat to
have a proper description how it is calculated and in which cases it should be
uses and in which it would fail.

> 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.
