maven仓库手动安装本地jar经典方法以及遇到的问题解决方法

1. 介绍
   在java开发过程中，经常会遇到一些包在maven仓库中无法下载的问题，如ojdbc,saxon等等，因此需要手动将本地jar包安装到maven仓库，来解决pom依赖的问题。
2. 方法
   ** maven添加本地包命令mvn install:install-file **

maven本地安装 xml2j

mvn install:install-file -Dfile=xml2j.jar -DgroupId=com.xml2j -DartifactId=xml2j-core -Dversion=2.5.0 -Dpackaging=jar

mvn install:install-file 标识通过文件方式安装
-Dfile 指定要上传的jar包
-DgroupId 制定包名
-DartifactId 制定上传后的jar项目名称
-Dversion 制定仓库中的版本号
-Dpackaging 打包方式

3. 问题与解决方法
   ** 3.1 本地打包遇到目录无效(windows powershell)**

解决办法：

通常是由于无法找到对应目录导致，需采用cmd进行打包，具体步骤如下：
# 切换盘符
e:
# 切换目录
cd E:\大数据\002.项目材料\003.爱建信托·风控系统\009.研发交付\002.道琼斯指数
# 打包
mvn install:install-file -Dfile=xml2j.jar -DgroupId=com.xml2j -DartifactId=xml2j-core -Dversion=2.5.0 -Dpackaging=jar
# 打包成功
E:\大数据\002.项目材料\003.爱建信托·风控系统\009.研发交付\002.道琼斯指数>mvn install:install-file -Dfile=saxon.jar -DgroupId=com.icl.saxon -DartifactId=saxon -Dversion=6.5.5 -Dpackaging=jar
