  File.open("jruby-complete.jar","wb") do |f|
    f.write(open("#{BASE_URL}/#{version_string}/jruby-complete-#{version_string}.jar").read)
  end
end

.download_jruby(jruby_version, force = false) ⇒ Object

Downloads the jruby-complete jar file for jruby_version and save in ~/.jruby-jar/jruby-complete.jar unless it already exits. If the jar is corrupt or an older version, set force to true to delete and re-download

.jarify_jrubyfx(src = "src/*", main_script = nil, target = "target", output_jar = "jrubyfx-app.jar", opts = {}) ⇒ Object

Creates a full jar from the given source pattern (must be a pattern to match files), with the given main script as the script to launch when the jarfile is run. The output jar is saved in the target dir, which also doubles as a temporary work dir. jar is the executable that makes jars. If target is nill then a random temporary directory is created, and output_jar is the full path to the jar file to save
