spring-rich is hosted at a different sourceforge repository from core spring. It is hosted here: http://sourceforge.net/projects/spring-rich-c
Everything in spring-rich-c is compiling and we strive very hard to keep a compiling and working state in CVS at all times to people can work off the latest enhancements (as we're still in rapid development mode.)
The code in spring-rcp within the core springframework project is obsolete -- from before we branched out to our own subproject on sourceforge. It's time to get sourceforge to delete the old spring-rcp module for us!
So again, you want spring-rich-c at sourceforge.net/projects/spring-rich-c. Our official project code name is "spring rich" :-)
