IMHO using something non-deterministic (like the p2 planner on a mutable p2 repository) and then adding constraints to it will _not_ yield a reproducible build.
It will work if there is only one possible solution to the problem. So it is theoretically possible to start with non-deterministic target platform and add enough constraints to essentially make all dependencies strict. I ran some prototypes couple of years ago. If project target platform is defined in terms of eclipse features, for example, then number of additional constraints necessary to make resolution fully reproducible is relatively small. -- Regards, Igor
