java - 将外部 jar 添加到 maven 本地存储库

Question

我是第一次使用maven。我正在尝试将 spring-core.jar 添加到我的本地 maven 仓库。我试图做的是

C:\Users\user\.m2\repository>mvn install:install-file -Dfile=C:\spring-core-4.2.0.RELEASE.jar -DgroupId=org.springframework -DartifactId=spring-core -Dversion=4.2.0.RELEASE -Dpackaging=jar

但我最终遇到了以下错误

请有人帮我解决这个错误，并让我知道如何将外部 jar 添加到我的 maven 存储库。谢谢

这条消息:

java.net.SocketException: Unrecognized Windows Sockets error: 10106: create

表示Maven无法打开10106端口，这个端口要么被阻塞要么被占用。

扫描端口，即在Windows下:

Windows+R ---> cmd ---> 输入
