Scala programs not getting auto-compiled in Eclipse

[Gunjan Rathii]

While writing Scala programs in Eclipse it is not getting auto-compiled with every save operation.

I am using the followings :
1. scala-2.8.1.final
2. Eclipse 3.7 M4 (Indigo)
3. jdk_1_5_06

I was expecting something similar to what I am used to while writing Java codes in Eclipse.
Please suggest.

I'm not sure if incremental compilation is supported yet for Scala on Eclipse.
