> Allow a Maven plugin to require a Java version through its plugin descriptor
> ----------------------------------------------------------------------------
>
> Key: MNG-7566
> URL: https://issues.apache.org/jira/browse/MNG-7566
> Project: Maven
> Issue Type: Improvement
> Reporter: Konrad Windszus
> Assignee: Konrad Windszus
> Priority: Major
>
> Currently a Maven plugin can only require a minimum Maven version via pom's
> prerequisites (https://maven.apache.org/pom.html#Prerequisites). There is
> currently no means to require a minimum Java version.
> I would suggest to slightly expand the plugin descriptor to include a
> minimumJavaVersion element there as well and evaluate that before executing a
> plugin goal and emit a good error message. The default Java version could be
> determined by the target class file version.
