So I have some XSDs for integrating with a third party supplier, which I need to convert to java classes. Easy, jaxb to the rescue!

Now when it comes to checking into source control, do I either a) check in generated files (bad) , or b) check in the XSDs and have maven generate my classes each time the project is packaged using its jaxb plugin (good).

Of course the senior dev picks option a), purely because some people in charge of support may not understand maven.

Why do I have to do things the wrong way because people don't want to learn/are incompetent? Why are there people in charge of support who don't understand simple tools?
