Maven ReadOnlyPluginParametersValidator triggered by tycho-p2-publisher

[Bananeweizen]

tycho-p2-publisher injects the build qualifier into the Maven model. However, on recent Maven versions that triggers one of the core validators: https://github.com/apache/maven/blob/master/maven-core/src/main/java/org/apache/maven/plugin/internal/ReadOnlyPluginParametersValidator.java

Therefore the goals of the p2-publisher then emit one warning each for having a value set for a read-only property. I'm not sure if there is a good way to work around the validation, but of course I would like to have my build show no warnings.

Sadly Maven has recently added a lot of validations that emit many warnings for code that previously worked without any issue and without any clear migration guide...

So, how to proceed? Can something be done on the Tycho side? Should we report this to Maven? Or what?
