I dont see the point of using Ant Build compared to executable Jars?

Question

I always think that to complete a project you successfully build it. And i thought that building is done automatically if you create an executable JAR? So what is ANT for?
Arent Executables is the same as building your project?

And furthermore you may find that the vast majority of your time programming professionally isn't the programming, but just managing these other aspects.It is a good day for me when that is not the case ;-)
There should be a class in university: "industrial practices". It would have little or no CS theory but all the stuff that you learn the first year on the job (often painfully).The company I work in really likes to hire young developers, which often means that they come right from school (gladly, we have some good IT-centric schools in the area). They usually get some introduction in some of these aspects in school (usually mostly version control, bug tracking and a little bit of automated builds). But even if they heard about them, used them for a simple project and get the general idea, they still don't believe them to be necessary until they see what a pain in the back it can be not to have all that in a medium-sized project.
