您可以使用:reset

Welcome to Scala version 2.10.0-RC2 (Java HotSpot(TM) 64-Bit Server VM, Java 1.6.0_37).
Type in expressions to have them evaluated.
Type :help for more information.

scala> val a = 1
a: Int = 1

scala> val b = 3
b: Int = 3

scala> :reset
Resetting interpreter state.
Forgetting this session history:

val a = 1
val b = 3

Forgetting all expression results and named terms: $intp, a, b
