Day to day I generally just run my product in the debugger - code changes are reflected immediately. However you can use p2 to update a previously exported product - although this requires exporting a new version of the product first to generate a compatible p2 repository. An alternative is to push your changes to a build server and have it build the new product and p2 repository for you.
