I see, but I think that your expectations are wrong. You want to build a project standalone, then you should change into that directory or use {{--file}} Always consider that Maven needs to calculate things to build one module out of a whole reactor. Maybe you can decompose your entire project into a smaller one.
I don't expect anyone to work on this any time soon.

>             Project: Maven
>          Issue Type: Improvement
>    Affects Versions: 3.5.4
>            Reporter: Morten Minke
>            Priority: Minor
>             Fix For: waiting-for-feedback, wontfix-candidate

> I have a project with the following setup:
>  
> {noformat}
> - MyProject
>   |- .mvn
>   |  |- maven.config
>   |  |- settings.xml
>   |- MyModule1
>   |  |- pom.xml
>   |- MyModule2
>   |  |- pom.xml
>   |- pom.xml{noformat}
>  
> The .mvn/maven.config file contains the following:
> {noformat}
> ..
> --settings .mvn/settings.xml{noformat}
> With this setup, I cannot build the modules separately because it cannot find the .mvn/settings.xml file in the MyModule1 directory.
>  
> I looked into the code and saw that in the mvn script, the .mvn folder is searched for in the parent folders. If it is found, that folder is marked as the 'maven.multiModuleProjectDirectory'.
>  
> However, as soon as the configuration is loaded, this multiModuleProjectDirectory is not used anymore for the interpretation of the --settings property, therefor maven tries to find the .mvn/settings.xml file inside the MyModule1 folder where it is not found.
> This results in an Exception and termination of Maven.
>  
> I thought of a couple of ways this could be solved:
>  * Allow for a variable substitution to work in the maven.config file and thus reference something like:
> {noformat}
> ..
> --settings ${baseDir}/.mvn/settings.xml{noformat}
>  * When the maven.multiModuleProjectDirectory is configured and the --settings flag is a relative directory, than use the maven.multiModuleProjectDirectory as the root to obtain the settings.xml file.
