将外部JAR包添加到Maven本地仓库

Question

将外部JAR包添加到Maven本地仓库

4

我第一次使用maven。我试图将spring-core.jar添加到我的本地maven仓库中。我尝试的方法是：

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，同时告诉我如何将外部JAR文件添加到我的Maven仓库。谢谢。

@letmedoit : 你能解释一下为什么需要手动将构件添加到本地的maven仓库吗？

依我之见，最好创建一个pom.xml文件并直接运行它。

在你的电脑上的某个位置添加这个文件（pom.xml）：


    <?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
      <modelVersion>4.0.0</modelVersion>
      <groupId>你的GroupId</groupId>
      <artifactId>你的ArtifactId</artifactId>
      <version>0-SNAPSHOT</version>
      <dependencies>
        <dependency>
          <groupId>org.springframework</groupId>
          <artifactId>spring-core</artifactId>
          <version>4.2.0.RELEASE</version>
        </dependency>
      </dependencies>
    </project>

然后只需在放置前述文件的目录中运行maven命令：mvn compile。

它应该执行构件的下载，如下所示：

这个消息：

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

意味着Maven无法打开端口10106。可能是该端口被阻止或者已经被占用。

扫描端口，例如在Windows下:

Windows+R ---> cmd ---> enter
netstat -b
