Tycho assumes that you are building for a plain OSGi runtime without any pre-existing "runtime" scope dependencies. So any unsatisfied dependencies will cause the bundles to not be resolved in the OSGi runtime, and Tycho already detects this in the build. If you have a version of the bundle that does resolve at runtime, just make that available in the build, and the build should also pass.

If there are multiple ways to resolve a dependency, Tycho (or more precisely Tycho's embedded p2 resolver) will pick one according to a pretty complicated optimization function. If you need to have control, make sure to only have the bundles in the target platform that you need. E.g. for p2 repositories, you can kick out some of the bundles by using filters [1]. For Maven POM dependencies, you can exclude items from the transitive dependencies by using the standard Maven dependency syntax.
