Is it possible with p2 to express negative dependencies, i.e., specifying an IU that must not be installed if my IU should be installed? |
If so, could that be used in the following scenario:
patch feature A_1.0.0
- replaces my.base_1.0.0 with my.base_1.0.0.EnhancementA
patch feature B_1.0.0
- replaces my.base_1.0.0 with my.base_1.0.0.EnhancementB
Here A and B are independent enhancements, neither subsumes the other.
If a user tries to install either A or B on top of the respective other I would like to see an error saying that both features are incompatible.
Later the provider of B might create
patch feature B_1.0.1
- replaces my.base[1.0.0,1.0.0.EnhancementA] with my.base_1.0.1.EnhancementB
Updating from A_1.0.0 to B_1.0.1 should be possible.
Is something along these lines possible?
