That is THE question ??? And it seems quite difficult to have a clear answer. Let’s recapitulate the information I gathered on this topic mainly related to build issues. Please feel free to comment on this post in order to complete or to correct what I am saying:
- No problem when building (Gui or headless) => all the required (the same than the required plugins computed in the launch configuration dialog when debugging the app) plugins are present
- The RCP application disk footprint is optimized !! No useless plugins
- No features are exported: as a result the features list tab of about dialog is empty !!!
- It seems that plugin products are not recommended for RCP with self update (I didnd’t tested that yet) ???
- When exporting (headless), the only present plugins and features are the one listed in the .product file
- Need to create a “dependencies” features including all the required plugins OR depend on all the features containing the required plugins => bring a lot of useless plugins
- Features listed in the about dialog
In my case, I decided to use a Feature Product and then to “manually” create a feature including all the 90 plugins required by my RCP.
Because I am lazy and hate repetitive tasks, I wrote a simple Java main parsing a launch configuration file (.launch located in the workspace metadata folder) and generating from a template the feature with all the required dependencies. Is there any other existing way to do that ??
Hope this can help others, and if you need my simple Java feature dependency creator, just ask it.
