I downloaded the glass-java-starter from github and followed all of the instructions on the glass developers site. I got it imported into Eclipse as a Maven existing project as instructed and I changed the oAuth file ID and Secret as specified. When I try to start the project or debug the project I am getting the following exception: Source not found for <http://cwiki.apache.org/confluence/display/MAVEN/NoGoalSpecifiedException>. The instructions give a command line command for running the project, $ mvn jetty, but nothing for Eclipse. How do I debug this project with Eclipse?
