Unless you specify "generateImplicitUnits=true" on the annotation the generator creates a minimal set of requirements. I
assume that the org.eclipse.emf.transaction feature is included transitively (aka "implicitely") through some other
feature. You can verify this assumption by activating the resulting .target file and inspect the respective target
definition content.

The target definition generator uses the actual resolution of all merged targlet *tasks* with all their targlets as a
basis to approximate a good .target file for the annotated targlet. Sometimes a low-level dependency (often some Orbit
stuff) are present in multiple repositories and then it's up to the generator to pick a random repository. You can
optimize the .target file in this regard by specifying "preferredRepositories=url1,url2,..." on the annotation.
