使用Nexus搭建maven私服

环境

• Ubuntu14.04 64位
• Jdk 1.8.0_60
• nexus-2.13.0-01-bundle
• maven 3.3.3

Nexus安装

下载

从Nexus官网下载开源版本Nexus OSS，选择自带jetty容器的bundle版本nexus-2.13.0-01-bundle.tar.gz：
http://www.sonatype.com/download-oss-sonatype
上述文件放在/opt目录下，并解压（tar -zxvf nexus-2.13.0-01-bundle.tar.gz），得到目录/opt/nexus-2.13.0-01。（以下操作的默认目录）

配置

• conf/nexus.properties文件
  配置运行端口以及工作目录，以下配置是的Nexus运行在8081端口，工作目录为/opt/sonatype-work。

application-port=8081
application-host=0.0.0.0
nexus-webapp=${bundleBasedir}/nexus
nexus-webapp-context-path=/nexus
nexus-work=${bundleBasedir}/../sonatype-work/nexus
runtime=${bundleBasedir}/nexus/WEB-INF

• bin/nexus文件
  简便起见，只配置一条信息，即使用root用户运行。

RUN_AS_USER=root

运行

使用以下命令运行：

bin/nexus start

可在浏览器查看是否运行成功，若出现后面的界面则说明运行成功。
点击右上角的登录，使用默认的admin/admin123登录。
http://10.110.13.141:8081/nexus/#welcome

配置文件

• 设置索引
  点击左侧的Repositories，在Repositories列出的多个库的Configuration的Deployment Policy选择Allow Redeploy；

下载远程索引（Download Remote Indexes）,选择True：

• maven的settings.xml
  配置了搭建的Nexus maven库的镜像地址，以及用户名和密码等。

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

项目通过Maven部署到Nexus

这里指本地开发的项目发布到Nexus的maven仓库中，以便小组其他成员依赖发布的jar包。
本地项目使用IntelliJ IDEA开发，需要在pom.xml文件中加入以下配置：

• 在project根目录下添加库信息

<groupId>com.inspur.sdk</groupId>
<artifactId>qiandu</artifactId>
<version>1.0-SNAPSHOT</version>
<repositories>
    <repository>
        <id>central</id>
        <name>Central</name>
        <url>http://10.110.13.141:8081/nexus/content/groups/public/</url>
        <releases>
            <enabled>true</enabled>
        </releases>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>
</repositories>
<pluginRepositories>
    <pluginRepository>
        <id>central</id>
        <name>Central</name>
        <url>http://10.110.13.141:8081/nexus/content/groups/public/</url>
        <releases>
            <enabled>true</enabled>
        </releases>
    </pluginRepository>
</pluginRepositories>
<distributionManagement>
    <repository>
        <id>releases</id>
        <name>Nexus Release Repository</name>
        <url>http://10.110.13.141:8081/nexus/content/repositories/releases/</url>
    </repository>
    <snapshotRepository>
        <id>snapshots</id>
        <name>Nexus Snapshots Repository</name>
        <url>http://10.110.13.141:8081/nexus/content/repositories/snapshots/</url>
    </snapshotRepository>
</distributionManagement>

• 在project/build/plugins下添加部署的plugin节点

<plugin>
    <artifactId>maven-deploy-plugin</artifactId>
    <version>2.8.1</version>
    <executions>
        <execution>
            <id>default-deploy</id>
            <phase>deploy</phase>
            <goals>
                <goal>deploy</goal>
            </goals>
        </execution>
    </executions>
</plugin>

完整的settings.xml和pom.xml文件见附件

• 部署到Nexus
  在terminal中运行以下命令：

mvn clean deploy

若显示以下信息则提示部署成功：

[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 15.934 s
[INFO] Finished at: 2016-07-14T20:22:41+08:00
[INFO] Final Memory: 29M/179M
[INFO] ------------------------------------------------------------------------

• 搜索依赖
  搜索qiandu，可以在Nexus 库中找到部署的依赖：

本地普通jar包部署到Nexus

• 选择3rd party或者Releases等库下的Artifact Upload
• 填写GAV 参数信息
• 选择上传的jar包
• Add Artifact
• Upload Artifact(s)

测试本地Nexus私服

新建maven项目，编写以下依赖，进行Maven测试：
