篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了maven中手动将jar包安装进仓库的方法及问题相关的知识，希望对你有一定的参考价值。
众所周知，我们只要在pom.xml文件中进行配置，maven就会自动下载jar包到本地仓库，那么，如果我们自己写一个jar包自己用，那么便无法通过配置来引用这个包，需要我们手动将包安装进仓库中。
我们使用命令mvn install:install-file -Dfile=your-jar-file-path -DgroupId=com.your.group -DartifactId=your-artifactId -Dversion=x.x -Dpackaging=jar在doc中进行jar的安装
-Dfile：指明需要安装的jar包所在的位置
-DgroupId：指明groupId
-DartifactId：指明artifactId
-Dversion：指明版本
上面的后三个参数对应pom文件中配置时的三个参数，两者要对应，pom文件中如下：
<dependency> <groupId>alipay</groupId> <artifactId>alipay</artifactId> <version>1.0.0</version> </dependency>
当我们执行这个命令时切记要在pom文件所在的路径下，否则会报如下错误(找不到pom文件)：
[INFO] Scanning for projects...

当我们进入pom文件路径下执行便会执行成功：

安装完之后我们打开本地仓库就会看到创建出了自己所加的文件路径，然后我们在pom文件中添加依赖就ok了
