将jar安装到本地mvn仓库

声明:仅限于将maven Repository下载的jar(使用maven打包的jar)安装到本地的maven仓库中,不保证全部成功,最初的时候添加依赖发现下载始终不成功,只能手动下载,但是手动下载完毕后,只能通过mvn install:install-file -Dfile=..这种方式安装jar包到仓库,实在是太过繁琐,仔细观察jar包后发现jar的坐标信息很容易从jar名称已经jar内部的pom.properties文件获得,代码如下

 package installJarToMVN;

 import java.io.BufferedReader;
 import java.io.File;
 import java.io.IOException;
 import java.io.InputStream;
 import java.io.InputStreamReader;
 import java.util.Enumeration;
 import java.util.jar.JarEntry;
 import java.util.jar.JarFile;
 import java.util.zip.ZipEntry;

  * version,artifactId可以从jar包名称获取,也可以从pom.properties获取

测试结果:

1.eclipse中运行

2.打包成jar

3.可以指定目录.默认的目录为d:/jartoMVN/ ,直接拷贝路径时记得加上 "/"
