Herv created MNG-7563:
-------------------------
Summary: Java system properties now overides user 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: 3.8.6, 3.8.5
Reporter: Herv
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 project 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).
