Stephen Connolly updated MNG-6172:
----------------------------------
Priority: Blocker (was: Major)
> Precedence of command-line system property options has changed
> --------------------------------------------------------------
>
> Key: MNG-6172
> URL: https://issues.apache.org/jira/browse/MNG-6172
> Project: Maven
> Issue Type: Bug
> Components: Command Line
> Affects Versions: 3.5.0-candidate
> Reporter: Stuart McCulloch
> Priority: Blocker
> Fix For: 3.5.0-candidate
>
>
> 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.
