------------------------------------------
Hi, could you make a concrete example of your problem? Furthermore
{{mavenre_pre}} to get command line parameters to do some checking? It's not
intended there..? The question is what kind of checks/verify/enforce you have
in mind?
Furthermore why not giving {{JAVA_HOME}} via command line? Like {{set
JAVA_HOME=...;mvn clean}} would work in Linux/MacOs etc ? I don't know if
something like this exists for Windows?
> Add command line parameters in 'mavenrc_pre' script

> Key: MNG-6648

> Project: Maven
> Issue Type: Improvement
> Components: Command Line
> Affects Versions: 3.6.0, 3.6.1
> Reporter: Alix Lourme
> Priority: Major

> Fix For: waiting-for-feedback

> 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
