I'm using maven 2.0.8. Here's what I get when I attempt to run: mvn package [INFO] Scanning for projects... [INFO] ------------------------------------------------------------------------ [ERROR] FATAL ERROR [INFO] ------------------------------------------------------------------------ [INFO] Error building POM (may not be this project's POM).
