----------------------------------

             Summary: User property no longer pushed to system properties
                 Key: MNG-8486
                 URL: https://issues.apache.org/jira/browse/MNG-8486
             Project: Maven
          Issue Type: Bug
    Affects Versions: 4.0.0-rc-2
            Reporter: Nils Breunese


I’m using jib-maven-plugin with some properties provided on the command line. 
According to 
https://github.com/GoogleContainerTools/jib/tree/master/jib-maven-plugin#system-properties
 this can be done as follows:

{code}
mvn compile jib:build -Djib.to.image=myregistry/myimage:latest
{code}

I’ve been successfully using the syntax above with Maven 3.9.9, but when I try 
this with Maven 4.0.0-rc-2 it seems that the ‘jib.to.image’ property is not 
picked up by jib-maven-plugin.

When I do this, it does work:

{code}
MAVEN_OPTS="-Djib.to.image=myregistry/myimage:latest” compile jib:build
{code}

I noticed that the Jib Maven Plugin documentation says that `jib.to.image` is a 
(Java) _system_ property, while technically `-D` on the Maven command line is 
for (Maven) _user_ properties.

I've [reported this on the Maven users 
mailinglist|https://lists.apache.org/thread/56fsshgwpb358dtw314khlpdylyffl4y] 
and [~cstamas] explained that although at some point Maven wants to stop 
pushing Maven user properties to Java system properties, this is not an 
intentional change for Maven 4.
