> Currently there is no way to script "get project version" in universal way that would work with Maven3 and Maven4. Assume you need construct like this to get project version:
> {noformat}
> version=$(./mvnw -q -DforceStdout --raw-streams help:evaluate -N -Dexpression=project.version) {noformat}
> But the problem is that Maven3 belly up on unknown {{--raw-streams}} option.
> Basically we have currently:
>  * Maven 3.9.9. belly up on {{--raw-streams}}
>  * Maven 4 must have, it otherwise construct will not return what you want
> Proposed solution: make Maven 3.9.10 silently ignore this option.
