MapBinder not available in Guice 3.0

MapBinder not available in Guice 3.0

This is rather strange that the MapBinder is not included in my Gucie 3.0
obtained from Maven repository:
My maven config is like:
<dependencies>
....
<dependency>
<groupId>com.google.inject</groupId>
<artifactId>guice</artifactId>
<version>3.0</version>
</dependency>
....
</dependencies>
My Guice 3.0 in the maven repository does not even have the package:
com.google.inject.multibindings
Can someone please point me out to the right direction?
Many thanks
