Hi Andreas, That looks like an issue specific to your setup. It seems it's not finding some of the other modules that the opcua driver and the example rely on. Can you build the entire project 'mvn clean && mvn install'?
If you could send through some more info, maven logs, etc.. it would be helpful.
