Hello Thorbjørn,

It is quite difficult to get Maven to do things it is not designed for, at least 
not out of the box. I do not know how to run unit tests after the jar is built. 
Usually, the jar is built, only if the tests pass. (Tests always come before the 
packaging.) For the various Maven2 test phases, see

   http://cvs.peopleware.be/training/maven/maven2/buildLifecyclePhases.html

We could run the test after the packaging phase, for example during the 
"integration-test" phase. I'll see what I can do.

On a related note, the addition of 
<argLine>-javaagent:${project.build.outputDirectory}=time</argLine>
seems to cause Continuum to fail. Here is the error message:

I'll look into this some more and get back to you.
