Builds failing with java.lang.NoClassDefFoundError

I have been trying to setup our prototype project to do an iOS or Web build but it continually fails with this error message: "
java.lang.NoClassDefFoundError: Could not initialize class org.eclipse.jgit.transport.URIish"

Below is the full build log. It looks like the build isn't able to get started properly. Anyone else encounter this one?
