I added these lines to the pom.xml file, and now the URCaps appear in ursim  
 ![pom_2](https://us1.discourse-cdn.com/flex020/uploads/universal_robots/original/2X/4/424215efaa5af7f10ff37f97378f1c8416d1a81f.png)

But now I get this error below. It does not seem to find the class I have used, but it is hopefully something small I have missed with importing the jar file. Anyone got an idea?

java.lang.NoClassDefFoundError: de/re/easymodbus/modbusclient/ModbusClient
