如何使用 Mercurial 下载源代码？我有兴趣从http://kenai.com/projects/javaee-patterns/sources/hg/show/AOPandJavaEE获取源代码。我安装了 Mercurial，我尝试过hg clone https://hg.kenai.com/hg/javaee-patterns~hg，但出现以下错误：
abort: error: A connection attempt failed because the connected party did not pr
operly respond after a period of time, or established connection failed because
connected host has failed to respond
它对我来说克隆成功：
$ hg clone https://hg.kenai.com/hg/javaee-patterns~hg

您的错误消息看起来像是您遇到了网络连接故障，但这更有可能与您的互联网连接有关，而不是与他们的连接有关。
您可以尝试执行 ahg init后跟 a hg pull -r 1 https://hg.kenai.com/hg/javaee-patterns~hg，它只提取第一个变更集，但这仅在您在下载时超时时才有帮助 - 您在最初连接时超时。
看起来如果您创建一个帐户并登录，他们会向您显示一个可能更强大的 ssh URL。
