      ~ N.B.: All dependencies for profiles are set in ./assembly/pom.xml
      ~ 
      ~ This is to prevent recursive dependencies. It's not ideal, but it works.
      ~ The parent project always builds first. Then, due to profile ordering here,
      ~ whatever modules are enabled are built. Finally, the assembly module is built,
      ~ which contains no actual code, but shades all its "dependencies" into one jar.

      ~ The interface and plugin modules should be built first to ensure that they are up to date.
