>             Project: Maven
>          Issue Type: Bug
>          Components: Command Line
>    Affects Versions: 3.5.0-candidate
>            Reporter: Stuart McCulloch
>            Assignee: Stephen Connolly
>            Priority: Blocker
>             Fix For: 3.5.0

>
> The current state of master (what will eventually become 3.5.0) has reversed the precedence of command-line system property options compared to previous releases of Maven.
> For example, running this command with a basic project:
> {code}
> mvn -Dmaven.repo.local=/tmp/aaa -Dmaven.repo.local=/tmp/zzz validate
> {code}
> using current master will cause {{/tmp/aaa}} to be created (first-one-wins), whereas for all previous releases of Maven {{/tmp/zzz}} would have been created (last-one-wins)
> This has the potential to break CI builds which relied on the previous last-one-wins behaviour.
> This was introduced by the fix for MNG-6078  https://github.com/apache/maven/commit/ca4303031357a7decaee8de770b71fb2c2fedd28 - by reversing the whole array the precedence between options on the same command line has been reversed, not just the relationship between .mvn/maven.config options and command line options.
