-------------------------------
Resolution: Fixed
Addressed with MNG-7634.
> REGRESSION: User properties now override model properties in dependencies
> -------------------------------------------------------------------------
>
> Key: MNG-7563
> URL: https://issues.apache.org/jira/browse/MNG-7563
> Project: Maven
> Issue Type: Bug
> Components: Dependencies, POM
> Affects Versions: 3.8.5, 3.8.6
> Reporter: Hervé Guillemet
> Assignee: Michael Osipov
> Priority: Major
> Fix For: 3.9.0, 4.0.0, 4.0.0-alpha-4, 3.8.7
>
> Attachments: poms.zip
>
>
> An important change has been introduced in 3.8.5 that breaks some existing
> builds: Java system properties now take precedence over default values of
> user properties in dependency POMs. This look like a bug since it's now easy
> to affect dependency behaviors with system properties, a practice that has
> been discouraged. But maybe do you consider this as a new feature ?
> As an example, 3 poms are attached to this ticket.
> After installing projects b and c, building project a with:
> {{mvn package -Ddep=x}}
> used to succeed until 3.8.4 (-D is ignored) but throws error with 3.8.5 and
> 3.8.6 (-D override the default).
> Note that without the setting of the default value for property {{dep}} in
> project b, the build fails with any version of Maven.
