Your example accesses Central Repository Index (http://repo1.maven.org/maven2), and due to bandwidth considerations, it does NOT index, hence index chunks you download does not have classNames in it.
Otherwise, your code looks good. Try the same against a Nexus repository with some JARs deployed, it will work. In short, Central repository uses "min" and "maven-plugin" set of creators, while Nexus uses "full" set of index creators. you can use Luke http://www.getopt.org/luke/ to inspect what downloaded index actually contains "min" is the bare minimum, and is always present, while others are "optional" creators.
