IT IS NOT UNCOMMON for teams that are otherwise highly disciplined about coding practices to neglect build scripts, either out of a belief that they are merely an unimportant detail or from a fear that they are complex and need to be tended to by the cult of release engineering.
Learn enough of your build process to know when and how to make changes. Build scripts are code. They are too important to be left to someone else, if for no other reason than because the application is not complete until it is built. The job of programming is not complete until we have delivered working software.
