Hello,

In some corner-case, you could have to run Maven with a custom {{JAVA_HOME}} (JDK v8, v11, ... even if it is evil some plugin can be impacted by JDK at runtime).

If it is per-project, [JVM and Command Line Options|https://maven.apache.org/docs/3.3.1/release-notes.html#JVM_and_Command_Line_Options] is not relevant and update {{JAVA_HOME}} each time in your environment could be boring.

A command line user-custom-parameter (ex : {{-Dmy.jdk=11}}) could be simple to achieve that.

A Maven script wrapper could be implemented for that, but it's like update the Maven distribution => evil.
The *mavenrc_pre* (MNGSITE-246) could be perfect for that feature !
But currently command line parameters are not used in script :(.

If parameters are used dor script call, sample for {{mvn.cmd}} (windows):
{code}
if exist "%USERPROFILE%\mavenrc_pre.cmd" call "%USERPROFILE%\mavenrc_pre.cmd %*"
{code}

It's allow any user customization, using Maven standards.

If relevant, I can provide PR.
Best regards
