OK, I ran the example ("mvn clean package") and the project builds
successfully on my system:
$ mvn -v

Well, it's 38 lines of code:
$ find . -name '*.java' | xargs wc
10 18 157 ./code/src/main/java/com/io7m/jarbug/Main.java
28 74 694
./resources/src/main/java/com/io7m/jarbug/MakeSources.java

If you just look at it, you can see that it doesn't do anything bad.

I am not the OP, and was not asking you to do anything. I was merely
inquiring whether you could perhaps avoid your company's bureaucracy via
some technical means.

I agree that it wouldn't hurt for the OP to post his error messages, too.
But that said, IMHO, posting a complete example project demonstrating the
issue is about the *best* thing you can do.
