Hi Michael, as similar to you I am not seeing any solution without the source I started yesterday night to look at the 0.7alpha. I resolved my build errors by refactoring some code - but next need to test if I can start OJ form the IDE with the new Sextante (which I still need compile...)
Though, as a note official Sextante is on 1.0.x, I am not sure how compatible sources still are... but the Algorithms seem to work (at least no build errors in the IDE. If they run is a different question).
