pull the latest changes from staging.
import it as existing java project( don't install buildship, or import it as a gradle project)
run gradle eclipseClasspath
now go to configure build path and then select the source tab remove everything except (DistributedSource/src) if no there just add it and apply.
also you no longer need that oldsdkpath line in gradle.properties( only for ds-frontend, other projects needs to worked on as well )

Now remember, this only stops eclipse from complaining about missing dependencies, you can safely ignore all these steps and your deployments would still be fine.
