don't know about the java command but I suspect some variation of this will do
it. (%x[ ] captures the output of command(s) executed within the square
brackets)
Facter.add("ruby_version") do
setcode do
ruby_version = "unknown"
rubypath = %x[facter rubysitedir]
ruby_version = %x[ruby -v | cut -f2 -d ' ']
ruby_version
end
end
