Cannot Build Scala Eclipse Plugin on Windows Vista x64

Maybe you have spaces in your classpath?

The specific IOException message is this:
 java.io.IOException: Cannot run program "C:\Program
Files\Java\jdk1.6.0_11\jre\bin\java.exe" (in directory
"C:\Users\Bret\workspace\scala\scala"): CreateProcess error=87, The
parameter is incorrect

After some google searches it seems this error is often associated
with the classpath being too long on Windows systems (which seems
likely since the build completes just fine on my MacBook). Any info as
to how to resolve this would be appreciated. Ive attached the full
console output from the build.

Thanks!

We just ran into this issue with the maven-scala-plugin.  It looks like scalac will need to support something like @files, and then we need to update the tools to use that.
For now, try hanging the scala root directory somewhere near a true root (Mine is C:\Projects\scala, but I'm using XP)

Moving the scala root did the trick for now! Thanks
