No goal should update a version to beyond the compatible Maven

[delanym]

The display-plugin-updates goal tells me some plugin updates are available and some are not (because my Maven version is not sufficient.)

[INFO] --- versions:2.17.1:display-plugin-updates (default-cli) @ ponyrides-build ---

When I follow this up with the update-properties goal the plugin updates all those plugins it said could not be upgraded. This should not happen.

I think its safe to say there's no need even to make this configurable. No plugin should ever be updated to a version beyond compatibility with the current Maven.

Is this a regression? Max version of thr Plugin that it worked as expected?

I tried with version 2.18.0, 2.14.0 and 2.12.0 and same behaviour - it always updates maven-compiler-plugin to 4.0.0-beta-1

Thanks for a quick response.
