-------------------------------------
Still no answer...
> Create M2_REPOSITORY env variable for Local Repository and Wrapper locations
> ----------------------------------------------------------------------------
>
> Key: MNG-7050
> URL: https://issues.apache.org/jira/browse/MNG-7050
> Project: Maven
> Issue Type: Improvement
> Components: Core, Maven Wrapper, Settings
> Affects Versions: 3.6.3
> Reporter: Manuel Jordan
> Priority: Minor
> Labels: features
> Fix For: waiting-for-feedback, wontfix-candidate
>
>
> 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.
