Updated to sbt 0.13.9; now I can not start sbt said I can not get Scala 2.10.5

Question

Windows 7, if sbt-0.13.9.msi is loaded and installed, the problem is the same as Why sbt 0.13.9 reports that it is 0.13.8? .

So, I installed with sbt-0.13.9.zip and deleted the .ivy2 \ cache and .sbt \ boot directory . But then sbt said it could not get Scala 2.10.5:

C:\Users\s001>sbt 
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0 
Getting Scala  2.10.5 (for sbt)...

            0 artifacts copied, 5 already retrieved (0kB/20ms) 
Error: Could not retrieve Scala 2.10.5: missing scala.Option, cala.tools.nsc.Global

But in below scala -2.10.5 \ lib is:

jansi.jar jline.jar scala-compiler.jar scala-library.jar scala-reflect.jar
