Though I have all my source in proper packages.It couldn't find at the time of Building Project.Normally it shows links everything.But at the time of Build Project or Autobuild while directly running project.
The import ecnet.rd.config cannot be resolved
In my experience, it is usual with Eclipse to have the build messed up. Make sure
Build automatically is checked and
Clean. If it doesn't work, restart Eclipse and do again.
Also as Tech Junkie comments below, try also
Clean all projects.
