Can you elaborate what you are doing, when you build, i.e. how do you build?  
And in what environment.

Also check out some of the deployment methods listed in the tutorial or [here](http://forum.universal-robots.com/t/urcap-deployment-methods/154).

Try to build it manualy with the command `mvn install` (in your urcap root).  
If it say “build sucess”, you can manualy copy the .urcap to your ~/ursim\*\*/programs ( `cp bin/<yourUrcap>.urcap ~/ursim**/programs/` ).  
Then you can install it via the ursim -\> setup -\> urcap etc.
