I set up a ruby installation, like

${WORKSPACE}/jruby/1.4.0

(this works with the ant plugin, so I tried it here) Then I created a job using this rake instance. In the log it says "FATAL: ${WORKSPACE}\bin\rake.bat doesn't exist"

Not sure why it would be looking for a .bat file on a linux machine, but I'm guessing it has to do with my windows master. Also, it's not honoring the path I set up, even if it said ${WORKSPACE}/jruby/1.4.0/bin/rake doesn't exist I would understand, but this is dropping everything.
