Eclipse: automatic execution and code generation during backup


I'm using Eclipse and I wanted to create a system that automatically generates java source code every time I save the project. More precisely I want to search for some files in a directory, generate static attributes for each of them and generate some methods every time the project is updated/saved. I thought that a piece of code that could be auto-executed by Eclipse would be fine, but I don't know if it's even possible. How can I achieve this behaviour?

You can specify a program or Ant script to be run when a project needs building in the 'Builders' section of the Properties for a Project.

You can also write an Eclipse plugin 'Incremental Builder' using the '' extension point. More information about this in the Eclipse help.
