The jars from the Google Code page are not directly runnable. You have to add 
the provided dependencies to your classpath and define the main class.

Alternatively or you can use the runnable fatjars with built-in dependencies. 
They are available from Maven Central, as described on the Google Code page:

http://search.maven.org/#search|ga|1|tudarmstadt.ukp

Use the "jar-with-dependencies.jar" for the component you want to run.
For the DataMachine, this would be
http://search.maven.org/remotecontent?filepath=de/tudarmstadt/ukp/wikipedia/de.t
udarmstadt.ukp.wikipedia.datamachine/0.8.0/de.tudarmstadt.ukp.wikipedia.datamach
ine-0.8.0-jar-with-dependencies.jar
