Jon Lorusso commented on MPH-71:
--------------------------------
I concur with previous comments.
I need a way to do something like this:
mvn help:evaluate -Dexpression=project.version
So that I can get at the pom's version, without (as has been said above)
parsing the pom myself. I am fairly surprised this type of functionality does
not exist in this or any other of the many many plugins out there.
> call help:evaluate in batch mode

> Key: MPH-71
> URL: http://jira.codehaus.org/browse/MPH-71
> Project: Maven 2.x Help Plugin
> Issue Type: Wish
> Affects Versions: 2.1
> Reporter: Galak
> Priority: Minor
>
> The help:evaluate goal is designed to be called in interactive mode.
> I would like to call this goal in batch mode, passing the expression to
> evaluate in a property (on the command line).
> The final purpose is to evaluate predefined expressions inside a script
> (unfortunately, the script is a batch file in my case...)
