>                 Key: MPH-144
>                 URL: https://issues.apache.org/jira/browse/MPH-144
>             Project: Maven Help Plugin
>          Issue Type: New Feature
>            Reporter: Karl Heinz Marbaise
>            Assignee: Karl Heinz Marbaise
>            Priority: Minor

> Currently if you  use {{mvn help:evaluate -Dexpression=project.groupId}} there will be
some lines generated with {{[INFO] ...]]}} If you use {{mvn help:evaluate -Dexpression=project.groupId
-q}} you won't get anything printed out.
> It would be a good idea to have an output via a supplemental parameter like this:
> {{mvn help:evaluate -Dexpression=project.groupId -Dstdout=true -q}} to get printed out
the information like this (:
> {code}
> 0.2.0-SNAPSHOT
> {code}
> this would give the opportunity to use the call within scripts etc.
> Also might be possible in one go:
> {{mvn help:evaluate -Dexpression=project.groupId -DoutputFile=result.txt -q}}
> to write the expression result into a file.
> Or the question is if it would be possible/good idea to print out the resulting expression
anyway (ignoring -q for only {{[INFO]...}} parts)
> {{mvn help:evaluate -Dexpression=project.groupId -q}}
