Artifactory远程P2存储库功能没有缓存所有的儿童位置

我想使用Artifactory Pro（版本4.14）作为几个外部P2存储库的代理。我的想法是，我们的Maven Tycho构建中的所有请求都超过了Artifactory的代理P2存储库。Artifactory远程P2存储库功能没有缓存所有的儿童位置

因此，我为Artifactory中的URL http://download.eclipse.org/releases/mars/创建了一个远程P2存储库，并在我的Maven Tycho构建中配置了此P2存储库（整个配置可以在here找到）。不幸，我的构建失败，因为java.net.ConnectException: Connection timed out: connect（整个错误日志，见下文）。

我的调查显示，原始P2存储库是一个复合P2存储库，其中一个子目录有http://download.eclipse.org/technology/epp/packages/mars/作为位置URL（您可以在compositeContent.xml中找到子目录位置）。 Maven Tycho试图直接连接这个孩子的位置。我的期望是Artifactory会用内部缓存变体替换这个URL，这样客户端不会直接访问远程子URL（比如Sonatype Nexus就可以做到这一点）。

这是唯一的配置问题？如果是这样，我可以在Artifactory中配置它吗？

我觉得才达到它在artifactory的创建虚拟存储库，并进入http://download.eclipse.org/releases/mars/远程URL的最佳途径。然后，您可以在tycho配置中使用虚拟存储库URL。这将为download.eclipse.org创建一个新的远程存储库，但不需要使用远程存储库。

有关更多信息，请参阅artifactory documentation。

使用虚拟存储库具有相同的结果。 –

@SandraParsick，它可能不起作用，因为你已经配置了不正确的远程存储库（在eclipse上），你需要先删除它们。使用P2和Artifactory的正确方法是创建虚拟存储库，将相关的远程存储库URL放入“P2存储库URL”字段中，让Artifactory为您创建远程存储库。此外，解决方案应通过虚拟存储库完成，而不是直接通过远程存储库完成。更多信息可以在这里找到：https://www.jfrog.com/confluence/display/RTF/P2+Repositories – Shayb

@Shayb我设置了一个虚拟仓库，就像它在维基中描述的一样，我在我的同样的错误信息建立。我将在artifactory的jira的bug中打开。 –
