Extending Eclipse product (parallel developments on a set of codes)

Question

A spawn off of an existing eclipse product is required for customization for a client. (hence parallel product development)

The intention was to use Eclipse Fragment, but "Fragments are additive, they cannot override content found in the host."

how can we maintain one set of codes in the svn, yet allow customization by overriding some classes?

---

the current solution is to have a global flag to indicated which product it is and "if" "else" littered everywhere in the codes ...

Answer 1

ehhh... by branching the code in SVN?

Answer 2

AFAIK there is no easy way of overriding a class in another plug-in.

Instead of overwriting you could define extension points or OSGi services, and the implementation of those can be replaced for the new client. For one client you could supply one extension/service implementation, and for the other the new one.
