Multimodule project with .mvn/settings.xml not working properly

I have a project with the following setup:

- MyProject
  |- .mvn
  |  |- maven.config
  |  |- settings.xml
  |- MyModule1
  |  |- pom.xml
  |- MyModule2
  |  |- pom.xml
  |- pom.xml

The .mvn/maven.config file contains the following:

..
--settings .mvn/settings.xml

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:

..
--settings ${baseDir}/.mvn/settings.xml

• 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.
