Create project-specific Maven settings

Question

I have a general settings.xml file for all Maven projects where a default profile and servers and mirrors are defined. How can I use project-specific settings to ignore the default?

Can I point to a local settings.xml file for one specific Maven project?

Passing a local settings file with --settings parameter also works but isn't there a way to do this permanently?

I think I have a solution to that problem, you need a recent maven version, I'm using maven 3.5.2 but the feature was introduced in maven 3.3.1 I believe, not sure.

The idea is to use the local .mvn folder (in the parent project's folder) where it is possible to configure several things like JVM options, maven options that are always used, etc.

For maven options just create a file maven.config inside the .mvn folder with the content --settings ./.mvn/local-settings.xml, and that should be about it. Of course the local-settings.xml should be a valid maven settings file.

Here's the structure within the maven project root folder :

parent-mvn-project    ├── .mvn    │   ├── local-settings.xml    │   └── maven.config    ├── submodule-A (if any submodules)    └── submodule-B (if any submodules)
