Basic Maven Help -- Can't Compile

I am trying to teach myself Maven. I bought a book. Im on the first example and can not seem to get it to work. I try to type "mvn compile" and it fails. Ive added the pom.xml file and the output. Can you point me in the right direction to get this to compile. Sorry for the formatting of the pom.xml. Im not sure how to get xml to display correctly. Thanks
