Question

我刚刚在公司代理服务器后面安装了Nexus 2.2-01。当我直接进入Central repo时，Maven正在工作，但当我在<mirror>中配置%M2_HOME%\conf\settings.xml时，我无法做一个简单的mvn archetype:create或mvn clean。

从Nexus网页用户界面我可以：

中环的“浏览远程”。
“浏览索引”
并从“Artifact Information”选项卡中显示“（非本地缓存）”我可以下载jar
然后在“http://127.0.0.1:8081/nexus/content/groups/public/”和“\ nexus \ sonatype-work \ nexus \ storage \ central中查看.jar和.jar.sha1文件“

...但由于某种原因，它不会下载.pom个文件

Nexus 2.2带有一个用于Central预配置的代理存储库，我可以从Web UI手动浏览索引和下载文件 - 那么为什么它不能在Maven中运行？

我已使用身份验证将默认HTTP代理设置配置为Nexus，但仍会出现以下错误：

[ERROR] Plugin org.apache.maven.plugins:maven-clean-plugin:2.4.1

Answer 1

哎呀！ DNS问题 - 使用maven settings.xml中的IP地址解决了问题。

Answer 2

另一个答案是正确的，但只是为那些遇到相同问题的人提供了一个注释，但上述答案并没有帮助：检查您的settings.xml代理设置。

Answer 3

I've seen this error today and the only thing that fixed it was going back to maven 3.2.5 (from 3.3.9)

Answer 4

为此，似乎

settings.xml中的代理部分引起了问题（您应该删除它们或修复它们）
您的Maven settings.xml中的URL问题

如果在其中正确定义了URL，则可能需要在以下位置打开hosts文件 C：\ Windows \ System32 \ drivers \ etc 并添加如下所示的行，将要连接的服务器映射到其相应的IP ...

11.111.11.11 RepoUrl

这样，您就可以声明名称为RepoUrl的baseurl实际上是IP 11.1。...

Nexus不会从Central下载工件
