I am trying to install the Scala in Eclipse Galileo 3.5, but I got the following error:

Error Message:

Scala IDE 2.0 only works with Eclipse 3.6 and 3.7. If you want to use Eclipse 3.5 you have to go with an older version, 1.0.

From the web page:

Current build is Scala IDE 2.0.0-beta8 with Scala 2.9.0.1 for Eclipse 3.6 and 3.7 (Helios and Indigo).

For Eclipse 3.5 (Galileo) and Scala 2.8.1.final support use the Scala IDE 1.0.0-milestones update site.

You can try it installing through market place.

Which works very fine without any problems.
