[MNG-8040] Allow prerequisites of maven plugins to define there minimum required java version

[jira-importer]

Christoph Läubrich opened MNG-8040 and commented

Currently the prerequisites of a maven-plugin to define a minimum maven version and then maven gives a nice message to the user if this is not meet.

Given the fast evolution of java versions plugins are facing another issue, e.g. if one of their dependencies require a higher java version than is the default for maven this currently fails with a rather cryptic "unsupported class version" error when running such a build.

It would therefore be good to extend the element so that plugins can declare:

<prerequisites>
     <maven>${minimal-maven-version}</maven>
     <java>${minimal-java-version}</java>
</prerequisites>

please note that using Maven Enforcer Plugin's is not an option here as it requires the user to know beforehand the java version of all its build plugins.
