在Linux下搭建自己的私有maven库并部署和发布自定义jar依赖和自定义maven插件(一)搭建SonatypeNexus私有库
文章目录
前言
上一节中我们分享了Sonatype Nexus私有库的搭建过程，今天给大家分享，如果将我们自己开发的jar文件部署到自己的私有库中。
一、部署已有的jar文件
在有些情况下，我们在做对接开发时，可能对方公司只会给我们发来一个jar文件，我们可以把jar文件安装到自己电脑的本地库里，但是当别的同事要使用时，又需要发给别的同事。特别是在多人开发的项目中，这种操作会很影响项目的开发进度，如果我们有自己的私有库，我们只需要把现有的jar文件部署到私有库中即可，最常用的有2中方式，
下面分解具体的操作方式。
填写相关信息即可
这种方式不需要登录到后台，直接在本地使用mvn命令即可，对程序员来说这种操作更方便快捷,具体步骤如下：
<server>
<id>user-release-nexus</id>
<username>admin</username>
<password>123456</password>
</server>
mvn deploy:deploy-file -DgroupId=com.test -DartifactId=csdn -Dversion=1.0.0 -Dpackaging=jar -Dfile=core-1.0.0.jar -Durl=http://192.168.101.170:8081/repository/maven-releases/ -DrepositoryId=user-release-nexus
执行命令完成后，我们登录Nexus验证一下是否上传成功。
说明我们已经上传成功了，这样在其他项目里面我们就可以加入下面配置来使用这个jar文件了：
<dependency>
<groupId>com.test</groupId>
<artifactId>csdn</artifactId>
<version>1.0.0</version>
</dependency>
二、部署自己的项目代码
首先我们准备一个普通的maven项目，pom.xml文件如下所示：
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.test</groupId>
<artifactId>test-nexus-jar</artifactId>
<version>1.0.134</version>
<packaging>jar</packaging>
<name>test-nexus-jar</name>
<description>test nexus jar</description>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<dependencies>
<dependency>
<groupId>commons-lang</groupId>
<artifactId>commons-lang</artifactId>
<version>2.6</version>
</dependency>
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.4</version>
</dependency>
</dependencies>
<distributionManagement>
<repository>
<id>user-release-nexus</id>
<name>User Project Release</name>
<url>http://192.168.101.170:8081/repository/maven-releases/</url>
</repository>
</distributionManagement>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.7.0</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-javadoc-plugin</artifactId>
<version>2.9.1</version>
<executions>
<execution>
<id>attach-javadocs</id>
<goals>
<goal>jar</goal>
</goals>
<configuration>
<additionalparam>-Xdoclint:none</additionalparam>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-source-plugin</artifactId>
<version>3.0.1</version>
<executions>
<execution>
<id>attach-sources</id>
<phase>verify</phase>
<goals>
<goal>jar-no-fork</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
其中distributionManagement标签定义了我们要上传的仓库地址，下面我们随意定义一个工具类，并定义几个方法，大体如下：
package com.test.csdn;
import org.apache.commons.lang.StringUtils;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class ProviderUtils {
public static final char UNDERLINE='_';
public static String underlineToCamel(String param){
if (StringUtils.isEmpty(param)){
return "";
}
StringBuilder sb=new StringBuilder(param);
Matcher mc= Pattern.compile("_").matcher(param);
int i=0;
while (mc.find()){
int position=mc.end()-(i++);
sb.replace(position-1,position+1,sb.substring(position,position+1).toUpperCase());
}
return sb.toString();
}
public static String camelToUnderline(String param){
if (StringUtils.isEmpty(param)){
return "";
}
int len=param.length();
StringBuilder sb=new StringBuilder(len);
for (int i = 0; i < len; i++) {
char c=param.charAt(i);
if (Character.isUpperCase(c)){
sb.append(UNDERLINE);
sb.append(Character.toLowerCase(c));
}else{
sb.append(c);
}
}
return sb.toString();
}
}
现在，我们来打包并部署：
mvn clean -DskipTests deploy
出现如下结果：
[INFO] --- maven-deploy-plugin:2.7:deploy (default-deploy) @ test-nexus-jar ---

说明我们已经部署成功了，到nexus后台检查：
发现我们刚才的项目也发布成功了，而且这里还生成了javadoc文件，还有源码sources文件也一并上传了。这样如果其他项目要使用我们的jar，在dependency标签里直接引用我们的jar包即可。
