Java EE 7 updatetool 安装失败

Question

我尝试使用 updatetool 安装 Java EE 7，以便能够运行 Java EE 教程示例。

但是updatetool安装失败。我尝试在我的基本操作系统上从命令行启动 updatetool 安装，然后在安装 updatetool 时看到错误。

错误文本示例 1:

输入/输出错误:URL http://pkg.oracle.com/javaeesdk/7/native/release/manifest/0/updatetool@2.3.5%2C0-56.2852%3A20111207T211721Z 连接失败:503:服务暂时不可用

Could not download application packages. This could be because:
  - a proxy server is needed to access the internet. Please ensure that
    the system proxy server settings are correct, or set the 'http_proxy'
    environment variable to the full URL of the proxy server.
  - the package server or network connection is slow.
    If you are getting time out errors you can try setting the
    PKG_CLIENT_CONNECT_TIMEOUT and PKG_CLIENT_READ_TIMEOUT
    environment variables and try again. For example to increase
    the timeouts to 300 seconds set them to 300
  - the package server is down or otherwise inaccessible or it is
    generating invalid data. Please contact the provider of the package
    server.

我不使用任何代理服务器。请帮忙!

Answer 1

我也有同样的情况 - 这是因为他们的网站速度慢得令人难以置信。

您显示的输出告诉您要做什么，增加超时。

但有时它只需要再次运行，这在我的情况下有效。
