The Maven Wrapper is an excellent choice for projects that need a specific version of Maven (or for users that don’t want to install Maven at all). Instead of installing many versions of it in the operating system, we can just use the project-specific wrapper script.

We can implement this if you want.

Added the PR for the wrapper... IMO, it would be best to make sure we have the right version of mvn defined, then we should have the CI build with the ./mvnw to ensure we are always building the expected mvn version. Happy to help there if desired.
