There’s an updated archetype for Tapestry-4.1.6-SNAPSHOT over at (the well known snapshot repo)

http://people.apache.org/repo/m2-snapshot-repository

All the hard work was done by Ulrich Stärk, so big thanks to him

For the record, here’s how to quickly generate a Tapestry project

mvn archetype:create -DarchetypeGroupId=org.apache.tapestry \
 -DarchetypeArtifactId=tapestry-archetype \
 -DarchetypeVersion=4.1.6-SNAPSHOT -DgroupId=org.example -DartifactId=myapp \
 -DremoteRepositories=http://people.apache.org/repo/m2-snapshot-repository
