I'm trying to follow the Pallet tutorial with vmfest.

I already added [org.clojars.tbatchelli/vboxjxpcom "4.3.4"] even though the tutorial didn't ask me to, because otherwise lein deps :tree didn't show vboxjxpcom at all, and I had the same error.

I'm guessing this is a series of version incompatibilities?

After banging my head against this for a while, I got it to work. You also need to add the vbox.home folder to java.library.path.

These are the jvm opts that got me past the compile error on Mac OSX:

  :jvm-opts ["-Dvbox.home=/Applications/VirtualBox.app/Contents/MacOS"
             "-Djava.library.path=%PATH%:/Applications/VirtualBox.app/Contents/MacOS"]
