The issue about what to do with external dependencies has not really been 
solved so I started looking at creating a “dependency-reduced” jar that uses an 
“include” clause and is from the assembly maven plug-in. It is at least far 
thinner than the current job.jar. One problem is that it includes a whole 
artifact so if you need one class you get all of Guava.
