lol, I am having a really similar problem right now.

Not sure if it's necessary since there is a ton of ide spring plugins that might do the job for you if you have them installed, but since we are using maven I am pretty sure that you will have to build your project with maven in order to do it right.

If you are using eclipse try something like Run as > Maven build... > goals: package (or just package it using the command line)

At least thats what I usually do. But I have a long record of bugs and problems with Maven and never really wanted to spend more time on learning something that seemed so ...unstable.(Once all of my dependencies were corrupted over night. I had to redownload some of them three times to fix all LOC header errors) So don't be surprised if this doesn't work for you.

Isnt really an answer but stackoverflow won't let me comment until I have 50 rep.
