How to execute a java class after cucumber tests in Maven?

I am new to tests and Maven and was asked to work with Cucumber. I manage to have good results but I still have to deal with the import of these results in Testlink.

To do that, I found a simple solution (http://ift.tt/29pFhAh) but the fact is that there is no maven dependency that matches with the proposed library.

So I choosed to create a XML document whose format corresponds to the one waited by Testlink but I now have another problem : how can I run the java class which contains this code after all my cucumber tests are done ? (and after the report results are done too)

Thank you !!
