String urlString = "https://butterfly.jenkov.com/"
+ "container/download/"
+ "jenkov-butterfly-container-2.9.9-beta.jar";
URL jarUrl = new URL(urlString);
JarURLConnection connection = new JarURLConnection(jarUrl);
Manifest manifest = connection.getManifest();
JarFile jarFile = connection.getJarFile();
