Preparing

To prepare, turn off automatic builds in Eclipse (otherwise, Eclipse is going to be really, really "helpful" by creating folders, modifying .classpath etc.). Keep automatic builds off until you've at least finished step 2 (changing your configuration files.

Once you've changed the configuration files, close the project and open it again, then turn on the Eclipse builds again.

1. Creating folders and moving stuff around

Here are the modifications you have to do to your project's layout, expressed in bash (as if your working directory is your project's root).
