I have tested JBoss AS 7 Quickstarts using JBoss AS 7.1. They are all deployed and started correctly.
M2e 1.0.100 seems to not update the Maven configuration automatically. Now, the Project Example engine updates the Maven configuration after importing a project example of the maven and mavenArchetype type.
I have updated JBoss AS 7 Quickstarts declarations in the project examples xml file so that they are valid for the JBoss AS 7.0/7.1 runtime.
The downloadId element is still showing JBoss AS 7.0.2 because it is the latest stable JBoss AS 7.
