举例子我们要将 elastic-job-spring-boot-starter安装到本地的maven仓库，如下：

<dependency>
            <groupId>com.github.yinjihuan</groupId>
            <artifactId>elastic-job-spring-boot-starter</artifactId>
            <version>1.0.5</version>
</dependency>

1.先去maven仓库找到这个包https://mvnrepository.com/artifact/com.github.yinjihuan/elastic-job-spring-boot-starter/1.0.5

2.右键下载pom和jar到本地 

3.安装jar到本地仓库

mvn install:install-file -Dfile=/Users/Desktop/elastic-job-spring-boot-starter-1.0.5.jar -DgroupId=com.github.yinjihuan -DartifactId=elastic-job-spring-boot-starter -Dversion=1.0.5 -Dpackaging=jar

安装pom到本地仓库

mvn install:install-file -Dfile=/Users/Desktop/eic-job-spring-boot-starter-1.0.5.pom -DgroupId=com.github.yinjihuan -DartifactId=elastic-job-spring-boot-starter -Dversion=1.0.5 -Dpackaging=pom

4.发布jar到nexus远程仓库

mvn deploy:deploy-file -DgroupId=com.github.yinjihuan -DartifactId=elastic-job-spring-boot-starter -Dversion=1.0.5--SNAPSHOT -Dpackaging=jar -Dfile=/Users/Desktop/elastic-job-spring-boot-starter-1.0.5.jar  -Durl=http://192.168.0.1:9966/nexus/repository/maven-snapshots/   -DrepositoryId=maven-snapshots 

发布pom到nexus远程仓库

mvn deploy:deploy-file -DgroupId=com.github.yinjihuan -DartifactId=elastic-job-spring-boot-starter -Dversion=1.0.5--SNAPSHOT -Dpackaging=pom -Dfile=/Users/Desktop/eic-job-spring-boot-starter-1.0.5.pom  -Durl=http://192.168.0.1:9966/nexus/repository/maven-snapshots/   -DrepositoryId=maven-snapshots
