In order to build the package your processes are in (in Guvnor) you have to set the correct package attribute to your process, otherwise the package will not build. Since your Guvnor package you are uploading the processes into is most likely not the same name as what the processes you are uploading have defined (since they are from jbpm examples module) you would need to open the process in Designer, locate the packages attribute for the process and change it to the name of the guvnor package it is in now.
