---------------------------------------
Summary: mvn help:evaluate -Dexpression=project.groupId Can't be
used in scripts.
Key: MPH-144
URL: https://issues.apache.org/jira/browse/MPH-144
Project: Maven Help Plugin
Issue Type: New Feature
Reporter: Karl Heinz Marbaise
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}}
