我正在尝试用gradle构建一个开源Java项目,lilith.但是从cmd行窗口运行gradle时遇到此问题:

D:\Opensource\lilith_svn\sulky-master>gradle

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'sulky-master'.
> Could not resolve all dependencies for configuration ':classpath'.
   > Could not resolve org.apache.maven.wagon:wagon-webdav-jackrabbit:1.0-beta-6

我正在尝试实现一个用于上传文件的烧瓶应用程序.这个文件可能非常大.例如,几乎2G的大小.

我已完成服务器端进程功能,如下所示:

@app.route("/upload/<filename>", methods=["POST", "PUT"])
def upload_process(filename):
    filename = secure_filename(filename)
    fileFullPath = os.path.join(application.config['UPLOAD_FOLDER'], filename)
    with open(fileFullPath, "wb") as f:
        chunk_size = 4096
        while True:
            chunk = flask.request.stream.read(chunk_size)
            if len(chunk) == 0:
                return

            f.write(chunk)
    return jsonify({'filename': filename})

至于浏览器方面,我应该给用户一个提交文件.一次一个文件.显示进度条以指示上载过程.但我不知道浏览器端代码.如何使用javascript代码开始上传并显示状态？
