I have the Eclipse IDE (Eclipse Java EE IDE for Web Developers. Version: Luna Service Release 1 (4.4.1)). Installed Scala IDE for eclipse version 3.0.x thru eclipe marketplace. But I'm not able to create a scala project , New -> project -> there is no scala option. I have scala 2.11, and sbt in my local machine, and scala is working from command prompt. Is that the problem of eclipse latest version?

Me too! In the eclipse error log (eclipse-workspace/.metadata/.plugins/org.eclipse.ui.workbench/log) I see the following:
org.osgi.framework.BundleException: Could not resolve module: org.scala-ide.sdt.core [852]
Bundle was not resolved because of a uses contraint violation.
org.osgi.service.resolver.ResolutionException: Uses constraint violation. Unable to resolve resource org.scala-ide.sdt.core [osgi.identity; osgi.identity="org.scala-ide.sdt.core"; type="osgi.bundle"; version:Version="4.0.0.m3-2_11-201407241647-33f4f20"; singleton:="true"] because it is exposed to package 'javax.xml.bind' from resources org.eclipse.osgi [osgi.identity; osgi.identity="org.eclipse.osgi"; type="osgi.bundle"; version:Version="3.10.0.v20140606-1445"; singleton:="true"] and javax.xml.bind [osgi.identity; osgi.identity="javax.xml.bind"; type="osgi.bundle"; version:Version="2.1.9.v201005080401"] via two dependency chains.
A bit of searching led to a conversation in the Scala-IDE google group and also Eclipse bug 430458.
The work-around is to add -clean to the top of your eclipse.ini file, which somehow changes the order in which dependencies are resolved.
Bonus tip: While you've got eclipse.ini open, up the JVM max heap size to 1024m.

I think Eclipse Luna version does not support scala IDE at all. You have any idea about it? – user3366706 Sep 15 '14 at 06:19

1There's currently (Sept 2014) a milestone release that works with Eclipse 4.4 (Luna): http://scala-ide.org/download/milestone.html#scala-ide-400-milestone-2 – cbare Sep 16 '14 at 03:54
