Change to the directory of the example module (wdtk-examples), then run:
mvn exec:java
-Dexec.mainClass="org.wikidata.wdtk.examples.DumpProcessingExample"
Thanks, that is exactly what I needed! :)
I understand that WDTK is a library to be used in your own applications, but I am often not patient enough to actually go and code up a whole app myself in a new dev environment before I actually see that the thing is running. So being able to actually start and run the example application is superuseful for my motivation, because now I can go ahead and tinker with it while it is running, and iteratively change it to what I want.
