Dear all,
I was going through the tutorial on how to use Google App Engine in
combination with Maven Archetypes:
https://developers.google.com/appengine/docs/java/tools/maven#installing_maven
It mentions that I need Maven 3.1 or newer, but when I reach the step where
we start a test server on localhost
mvn appengine:devserver
I get the following error:

Is this a well known limitation (Maven 3.1), because when I stepped back to
Maven 3.0.5, everything is working fine...?
Maybe something to update in the documentation or FAQ section...?
Kind regards,
Bart
