你有没有给你的每个任务设置 path ？或者 filename ? 直接出示一下你如果初始化你的多个 Task 的？

[hellozengms]

final List<BaseDownloadTask> tasks = new ArrayList<>();
    FileDownloadQueueSet queueSet = new FileDownloadQueueSet(new FileDownloadListener() {
        @Override
        protected void pending(BaseDownloadTask task, int soFarBytes, int totalBytes) {
        }

        @Override
        protected void progress(BaseDownloadTask task, int soFarBytes, int totalBytes) {
        }

        @Override
        protected void completed(BaseDownloadTask task) {

        }

        @Override
        protected void paused(BaseDownloadTask task, int soFarBytes, int totalBytes) {

        }

        @Override
        protected void error(BaseDownloadTask task, Throwable e) {

        }

        @Override
        protected void warn(BaseDownloadTask task) {

        }
    });
    for (String url : urls) {
        tasks.add(FileDownloader.getImpl().create(url)
                .setTag(url).setPath(dirPath, true));
    }
    queueSet.disableCallbackProgressTimes();
    queueSet.setSyncCallback(isSync);
    queueSet.setAutoRetryTimes(3);
    queueSet.setForceReDownload(true);
    // 并行下载
    queueSet.downloadTogether(tasks);
    queueSet.start();

你的 dirPath 有没有可能为空？

这个问题，我能复现的，使用一个无法访问会返回404的链接，传递路径使用setPath(dirPath, true)，就会出现空指针异常
