Nils Breunese commented on MNG-5659:
------------------------------------
I'm not sure I'd be considered as someone mastering Maven (although they do
call me Dr. Pom at work :)), but at my company we have over 1000+ Maven
projects with project-specific {{settings.xml}} files, because it is just
super-valuable for projects to be buildable right after cloning them, requiring
no more than a JDK installed on the host system. Maven Wrapper pulls in the
configured Maven version and {{.mvn/maven.config}} contains
{{--settings=.mvn/settings.xml}} for the project-specific settings.
This setup works fine as long as you always call {{./mvnw}} from the root of a
project, but breaks down when you want to run Maven from a
subdirectory/submodule, because suddenly {{--settings=.mvn/settings.xml}}
points to the wrong location. If Maven would always look for {{settings.xml}}
in a specific project-specific location, then we would be able to drop the
{{--settings}} entry from all {{.mvn/maven.config}} files and just run Maven
from anywhere in a project.

> It would be useful to have a settings.xml file next to the project pom that
> could contain project specific settings. For example, when switching between
> projects it is sometimes necessary to also change the location of the local
> repository, or use a different set of repositories and/or mirror settings for
> each project.
> If a settings.xml file could be included with a project checkout, then the
> repositories needed for the build could be included (instead of putting them
> in the pom) along with any other project specific settings.
> The tricky part is intelligently handling multi-module projects. For a
> multi-module project I don't want to include a separate settings.xml file for
> each directory. So Maven could recursively check each parent directory until
> it either (1) finds a settings.xml, (2) finds a directory with no pom.xml, or
> (3) finds the root directory.
