Load whole project from Eclipse(about source code)

I am working on buid a plugin of Eclipse. In one step, i load the project through scan classpath,but the feedback from requirement is:

Loading projects encompasses two things:

1. Loading multiple files from the same directory/package
2. Including files from other packages through for instance Eclipse开发者_如何学运维's .classpath files

Since the prototype will be built into an Eclipse plugin anyways, is it fine to use Eclipse stuff, like the .classpath files? you are now loading and reading these files yourself. It might be more convenient to use Eclipse code for this, since it has to be already there.

I have no idea how to deal with it from Eclipse, can anybody help?

I think you're looking for PDE build. You could have a look at this tutorial.
