[scala-ide-user] scala.tools.nsc.MissingRequirementError: object scala not found.

I'm trying to use the latest version of the Eclipse support, and I'm
seeing lots of these errors:

eclipse.buildId=unknown
java.version=1.6.0_18
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US
Framework arguments: -product org.eclipse.epp.package.java.product
Command-line arguments: -os win32 -ws win32 -arch x86 -product

The about page says that I'm running 2.8.0.RC2.

I'm on Windows 7. Works fine on my Macs.

Suggestions? I've removed the plugin completely and reinstalled, that
didn't seem to make any difference.

scala-library.jar wasn't on the classpath for the project. (I had
checked in stuff from a mac, so I had a non-existant path to it in the
project when I was trying to use it on my Win7 box.).

Can I see your .classpath and .project files?

Cheers,


Miles
