Maven手动安装jar包（遇见pom无论如何都下载不了的依赖jar包处理方式）

有时候我们的maven项目会遇到无论怎么下载，怎么配置都有下载不了的jar包，这时候就需要我们手动安装jar包了。

比如下面这个maven-source-plugin，不论我如何操作，就是无法下载。

2、maven如何手动安装jar包

在idea的maven窗口中输入以下命令：

mvn install:install-file -Dfile=I:/360Download/maven-source-plugin-3.2.1.jar -DgroupId=org.apache.maven.plugins -DartifactId=maven-source-plugin -Dversion=3.2.1 -Dpackaging=jar

参数说明：

-Dfile ： jar包的路径-DgroupId

-DgroupId ： groupId

-DartifactId : artifactId

-Dversion : 版本号

四个参数都需要根据实际填写。

安装过程：
