How define for Maven's Environment Variable to define Local Repository and Wrapper download location?

I need do mention about Gradle to understand and find the same solution for Maven.

In Gradle exists the GRADLE_HOME and GRADLE_USER_HOME (repository) environment variables, for Maven the former through M2_HOME and about the repository I use the settings.xml file to define the <localRepository> location

For both Maven and Gradle I can define in peace the place about where is installed the software, for example other location than .m2 and .gradle to a secondary disk and even with customized directory names. Same goal about the repository location, both for a secondary disk (remember for Maven through the settings.xml file)

Note: therefore .gradle and .m2 are empty and not used.

In Gradle about the wrapper created, the gradle-wrapper.properties file has:

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-#.#.#-bin.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

Then the final path is: GRADLE_USER_HOME/wrapper/dists Therefore observe how GRADLE_USER_HOME (custom location - otherwise .gradle by default) is used to define the:

Goal: How accomplish the same behaviour for Maven? I mean, what should be the environment variable name (something like MAVEN_USER_HOME) for the local repository that Maven should recognize automatically? (not using the settings.xml file). It with the purpose to have any Maven wrapper installed according that environment variable name configured (custom location - otherwise .m2 by default) and of course defined the Local Repository too.

Therefore: I need the maven-wrapper.properties using something like MAVEN_USER_HOME (custom location - otherwise .m2 by default) according the developer/user in its machine.

For me, I am using spring boot boilerplate code that is generated from spring.io. Inside come with mvnw.cmd. By setting MAVEN_USER_HOME to a customized location, running mvnw.cmd will download the maven to that customized location.

Once done, I still need to manually go to that downloaded maven location to configure the settings.xml to point to a customized location for the maven libraries repo.

So at the moment, sadly, seem like the settings.xml is required to configure the repo, and MAVEN_USER_HOME environment variable has nothing to do with the repo.
