Hi Stephen,
it is allowed to manually override the version in a child project.
This does not defeat the point of depMgmt, in my opinion. So why should
the versions-maven-plugin should be able to do it, too?
We have a parent pom with "official" versions but want to build child
projects with "unofficial" versions. This is where we want to override
the version in the child pom.
I am searching for a solution for a build pipeline where a project A is
build using the latest version of project B. Perhaps I can achieve what
I want by using some kind of "unofficial" parent pom whose versions are
updated as you suggested. I will see.
I tried to patch your plugin such that it is able to add a version
element to the pom. Perhaps you'll want to use it if you change your mind.
Thanks for your answers.
Best regards
Achim
