error while compiling reflect in scala source

[Chifeng Chou]

Hi there,

I checkout the most up-to-date scala code and follow http://scala-ide.org/docs/tutorials/scalac-trunk/index.html
scala-library, asm, continuations-library are compiled in order without problem. However, an error appears while compiling reflect. From log:

2013-04-24 22:07:46,696 ERROR [main] - org.scala-ide.sdt.core - org.scala-ide.sdt.core - org.scala-ide.sdt.core - 0 - Error in Scala compiler

SBT builder crashed while compiling. The error message is 'class scala.annotation.serializable in compiler mirror not found.'.
Do I miss anything? How can I fix this? Thank you.
