我正在尝试将我们的Jenkins服务器连接到我们的Artifactory存储库以进行构建。我在办公室的位置上成功使用了Jenkins服务器，但我遇到了Jenkins服务器的问题，该服务器位于公司网络的另一部分。
我已停用该作业，进入工作区，并尝试直接使用mvn：
$ mvn clean

但是，如果我尝试通过curl获取该网址，则会毫无问题地下载。与wget相同：
$ curl http://repo.vegicorp.net/artifactory/plugins-release/org/apache/maven/plugins/maven-clean-plugin/2.4.1/maven-clean-plugin-2.4.1.pom

因此，我可以通过wget和curl访问该网址，但Maven本身似乎在获取该网址时遇到了问题。我已将proxy设置添加到~/.m2/settings.xml，但这似乎没有任何区别。我们最初设置我们的Maven存储库以从端口80重定向到端口8080，但是从URL添加或删除端口号没有区别。 settings.xml来自Artifactory，它将为您生成它。同样的settings.xml在我们办公室工作。
删除settings.xml可以使一切正常，因为它可以从标准的Maven仓库下载。

这看起来像代理设置问题。你能否在这个问题上添加mvn help：有效设置的ouptut？谢谢！
我要哭了......

对不起。由于我的设置，我无法运行mvn help:effective-settings ...
