I'm working on a Java application that uses JavaSpace. We're developing this in Eclipse. There are a couple instances where we are inserting code into the JavaSpace to do some more advanced space notification logic. Doing this requires that we generate stubs for the classes used within the JavaSpace. We use an external script to generate these stubs.

The problem is that whenever Eclipse restarts, it does a clean build of the whole application. When it does this, it deletes all the stubs and we have to regenerate them.

I would like to find a way to either tell Eclipse not to remove the _stub.class and _skel.class files within the bin folder where the .class files are placed. Either that, or somehow teach Eclipse to generate the stub files whenever it does a rebuild (and I suppose whenever the source files from which the stubs are generated changes).

How can I do one of these, so that we don't have to manually build the stubs every time we start up Eclipse?
