Locally deploying Glass Java starter project, AuthFilter ClassNotFoundException

I've followed the steps in the Java Quick Start to the letter. When trying to deploy locally, I get the following stacktrace:

Any ideas on where I'm going wrong? I've copied over the appropriate values to oauth.properties and appengine-web.xml.

I've double-checked my client IDs, even generating new ones and deleting the old ones, and everything seems to be in order.

For the Java quickstart project, be sure to do a mvn compile first:

mvn compile

Then, run it:

dev_appserver.sh ./web/

The quickstart instructions omit the compile step, so following them to the letter will get you in trouble :)
