Erros when importing project in Eclipse

[RHRawal]

I could work on the project through sbt, I also issued eclipse or eclipse -with-source=true commands before going to Eclipse to import the project. On importing it showed these problems:
/hello-scaloid-sbt/gen already exists but is not a source folder. Convert to asource folder or rename it.
Error in scala compiler object scala.runtime in compiler mirror not found
Sbt builder crashed while compiling. The error message is object scala.runtime in compiler mirror not found
Before that it also gave message of duplicate entries src in .path
I am using current eclipse, scalaide and adt versions. This is my first attempt at familiarizing scaloid. Could I know where am I going wrong? Thanks. Ramesh,
