Nexus 无法下载 spring-boot 的依赖

Question

我正在使用一个我没有配置的关系。我在运行 Windows Server 2012 的系统上使用远程桌面登录。当我想构建我的 spring-boot 应用程序并运行目标 mvn clean package 时，它​​会下载几个依赖项，然后因连接被拒绝错误而失败。我不明白这个。为什么可以下载前几个，但不能下载 spring-boot-starter-aop jar？什么连接被拒绝？是用来下载其他的吗？这是我的错误报告：

Answer 1

它没有下载任何一个。

如果您查看订单，它实际上是第一个 Downloading: http://192.168.1.142:8081/nexus/content/groups/public/org/aspectj/aspectjweaver/1.9.6/aspectjweaver-1.9.6.pom 失败。

它告诉你它正在下载，但在第一次尝试时它无法连接。

我的建议是先在没有maven的浏览器上试试这个URL，看看能不能访问：浏览器中的http://192.168.1.142:8081/nexus/content/groups/public/
