How to keep ANT build script up to date?

[Den P]

Hello,

I'm using Jenkins to build and test a large Java program.

Jenkins and the ANT build script are working perfectly.

Since different developers are still adding code and new classes to the program, the structure of the program is changing all the time. 

Now here the question: 

Is there any way to keep the ANT build script up to date according to the current structure of the program? Or are there any tools available to auto-generate the ANT script from the repository?

Thanks in advance for your help!
