Formatting a simple string, but `java.lang.NoSuchMethodError`

I'm using Scala 2.9.2.

Run Scala and test a simple code, this code is… OK:

...
val title = "Hashing file (%s)..." format sizeToStr(file.length)

But I couldn't understand what is what, while I put that code into a simple app, compiling OK, at runtime it throws this one:

java.lang.NoSuchMethodError: scala.Predef$.augmentString(Ljava/lang/String;)Lscala/collection/immutable/StringOps;

Could you please help me out? Thanks.

It seems like you're compiling against a different version of the standard library than you're using at runtime.
