Fri, 5 Oct 2018 15:57:05 +0000

While building Controller project, Maven prints several warnings, most originating from config subsystem.

Currently on Nitrogen (visible in merge job console log):

[WARNING]
[WARNING] It is highly recommended to fix these problems because they threaten the stability of your build.
[WARNING]
[WARNING] For this reason, future Maven versions might no longer support building such malformed projects.
[WARNING]

According to Stack Overflow information [0] (might be outdated) version information included in dependencyManagement does not apply for plugin versions, so importing

{project}

-artifacts is not enough.

To fix, either specify plugin version explicitly in every use, or employ pluginManagement somehow.
