> I need do mention about Gradle to understand and find the same solution or approach 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:
>   
> {code:java}
> distributionBase=GRADLE_USER_HOME
> distributionPath=wrapper/dists
> distributionUrl=https\://services.gradle.org/distributions/gradle-#.#.#-bin.zip
> zipStoreBase=GRADLE_USER_HOME
> zipStorePath=wrapper/dists
> {code}
> 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:
>  * Local repository
>  * Base path to install the downloaded Gradle through the wrapper
> *New Improvement*: Add for Maven an environment variable named M2_REPOSITORY for the _Local Repository_ and _Wrapper Installation_ locations that Maven should recognize automatically (*not* using the {{settings.xml}} file).
> It with the purpose to have any Maven wrapper(s) installed according to that _environment variable_ value (custom location - otherwise {{.m2}} by default) and of course applied for the Local Repository location too.
> *Observation*: If the {{settings.xml}} file exists it should override the M2_REPOSITORY value. 
> *Therefore*: I need the {{maven-wrapper.properties}} using something like {{M2_REPOSITORY}} (custom location - otherwise {{.m2}} by default) according the developer/user in its machine.
