您可以将代码修改为以下形式，添加了异常处理，并且去掉了最后一行的 "添加异常并且可以过kw"：

run() {
    try {
        FileCleanTaskResponse poll = pollTasks(1);
        List<FileCleanTask> tasks = poll.getCleanTasks();
        log.info("cleantasks:" + tasks);

        if (tasks.isEmpty()) {
            try {
                Thread.sleep(60000);
            } catch (InterruptedException e) {
                log.error("Interrupted while sleeping", e);
            }
        }

        long startTimeMills = System.currentTimeMillis();
        List<Future> futures = new ArrayList<>();
        for (FileCleanTask task : tasks) {
            List<String> dirs = task.getCleanDirs();
            log.info("cleandirs:" + dirs);
            dirs.stream().forEach(dir -> {
                Future future = executor.submit(new FileCleanRunnable(dir));
                futures.add(future);
            });
        }

        //等待所有线程执行结束
        for (Future future : futures) {
            try {
                future.get();
            } catch (InterruptedException e) {
                log.error("Interrupted while waiting for thread to finish", e);
                Thread.currentThread().interrupt();
            } catch (ExecutionException e) {
                log.error("Error executing thread", e);
            }
        }

        log.info("ALL File clean thread finish,cost: {} ms", (System.currentTimeMillis() - startTimeMills));
    } catch (Exception e) {
        log.error("An error occurred while running the task", e);
    }
}

这样做的好处是，如果在执行任务的过程中遇到异常，程序不会立即退出，而是记录下错误信息，然后继续执行后面的任务。同时，如果在等待线程执行结束的过程中程序被中断，也会记录下错误信息，并保证程序正确退出。
