我正在尝试按照此处的步骤在 podman 上构建一个用于开放自由的容器 - https://openliberty.io/guides/containerize-podman.html.
看起来 RUN features.sh 步骤失败，因为它无法访问互联网，但这是一个奇怪的错误。 我在这个容器上运行了 yum install nano 和curl www.google.com，它们都成功了。 为什么这些命令可以访问互联网，但features.sh却不能？
我得到的错误如下。 另外，为什么错误引用了maven而不是open liberty？ 仅供参考，我在工作中运行此程序，因此涉及网络代理，但从我的桌面来看，代理是透明的。

CWWKF1390E: The configured Maven Repository cannot be reached. Verify that your computer has network access and firewalls are configured correctly, then try the action again. If the connection still fails, the repository server might be temporarily unavailable.
featureUtility 从 Maven 存储库下载功能，如果未提供配置，则默认为 Maven Central。该消息引用 Maven 而不是 Open Liberty 的原因是它正在尝试连接到 Maven 存储库。我不知道您运行 Podman 构建的环境，但您可能在 Maven Central 被防火墙规则阻止的环境中运行它。很可能 Maven Central 被阻止，但 yum 存储库和 google 没有被阻止。一种快速测试方法是在容器中运行
