### Question:
SSH2Util { public static String mkdir(Machine machine, String path, boolean sudo) throws Exception { StringBuilder command = new StringBuilder(); if (sudo) { command.append("sudo "); } command.append("mkdir -p ").append(path); return execute(machine, command.toString()); } private  SSH2Util(); static void wget(Machine machine, String targetPath, String fileName, String remoteUrl, boolean sudo); static String copy(Machine machine, String originalPath, String targetPath, boolean sudo); static String copy2(Machine machine, String originalPath, String targetPath, boolean sudo); static String copyFileToRemote(Machine machine, String tempPath, String url, boolean sudo); static String rm(Machine machine, String filePath, boolean sudo); static String unzipToTargetPath(Machine machine, String filePath, String targetPath, boolean sudo); static String mkdir(Machine machine, String path, boolean sudo); static String execute(Machine machine, String commands); @Deprecated static String localExecute(String command); static Connection getConnection(Machine machine);  }### Answer:
@Test public void mkdir() throws Exception { SSH2Util.mkdir(machine, DockerNodeOperation.DOCKER_INSTALL_BASE_PATH + "cluster", true); }
