Linux下使用nexus搭建maven私服

下载安装

最新nexus下载地址：http://www.sonatype.org/nexus/go

解压后会在同级目录中，出现两个文件夹：nexus-oss-webapp-1.8.0和sonatype-work，前者包含了nexus的运行环境和应用程序，后者包含了你自己的配置和数据。

$ mkdir nexus$ tar xzvf /home/jili/nexus-2.7.0-05-bundle.tar.gz$ lsnexus-2.7.0-05  sonatype-work

启动nexus

$ cd bin/$ lsjsw  nexus  nexus.bat$ ./nexusUsage: ./nexus { console | start | stop | restart | status | dump }$ ./nexus startStarting Nexus OSS...Started Nexus OSS.

查看控制台：

$ ./nexus console

显示未启动成功，报错如下：

原因：查找原因是JDK版本过低造成的，升级到最新的JDK7或者使用nexus-2.4-bundle.tar.gz版本JDK6会支持.

Nexus所有版本下载地址：http://www.sonatype.org/nexus/archived

下载Nexus2.4重来

$ lsnexus-2.4.0-09  sonatype-work$ cd nexus-2.4.0-09/bin/$ lsjsw  nexus  nexus.bat$ ./nexusUsage: ./nexus { console | start | stop | restart | status | dump }$ ./nexus startStarting Nexus OSS...Started Nexus OSS.$ ./nexus consoleRunning Nexus OSS...Nexus OSS is already running.

控制台显示启动成功。

查看nexus日志：

$ cd nexus-2.4.0-09/logs$ lswrapper.log$ tail -f wrapper.log

配置nexus

访问网址：http://yourhostname:8081/nexus

右上角以admin登陆，默认用户名/密码：admin/admin123。

3rd party、Snapshots、Releases这三个，分别用来保存第三方jar、项目组内部的快照、项目组内部的发布版.

手动添加第三方jar

将第三方的jar上传到nexus上面：

点击Upload Artifact(s)按钮提交后即上传。

查看上传的jar包如下：

在项目中使用私服的jar包配置pom.xml如下：

<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/maven-v4_0_0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>com.vclk.mkt.crawler</groupId>  <artifactId>MarketingCrawler</artifactId>  <packaging>jar</packaging>  <version>0.3</version>  <name>MarketingCrawler</name>  <url>http://maven.apache.org</url>  <!-- 仓库地址 -->  <repositories>      <repository>          <id>nexus</id>          <name>Team Nexus Repository</name>          <url>http://yourhostname:8081/nexus/content/groups/public</url>      </repository>  </repositories>    <!-- 插件地址 -->  <pluginRepositories>      <pluginRepository>          <id>nexus</id>          <name>Team Nexus Repository</name>          <url>http://yourhostname:8081/nexus/content/groups/public</url>      </pluginRepository>  </pluginRepositories>  <!-- jar -->  <dependencies>      <dependency>          <groupId>de.innosystec</groupId>          <artifactId>java-unrar</artifactId>          <version>0.5</version>      </dependency>  </dependencies></project>

Maven在项目根目录下执行mvn eclipse:eclipse命令时，所依赖的jar包都会从私服中下载到本地并关联上项目，私服中没有就会从网络上下载到私服，本地再从私服下载。

自动发布构件到远程仓库

在工程的pom.xml中添加：

<distributionManagement>  <repository>      <id>nexus-releases</id>      <url>http://yourhostname:8081/nexus/content/repositories/releases/</url>  </repository>  <snapshotRepository>      <id>nexus-snapshots</id>      <url>http://yourhostname:8081/nexus/content/repositories/snapshots/</url>  </snapshotRepository></distributionManagement>

进入maven的安装目录apache-maven-3.1.1\conf目录下，向settings.xml配置文件中的语句块中添加如下所示：

<servers>  <server>      <id>nexus-releases</id>      <username>admin</username>      <password>admin123</password>  </server>  <server>      <id>nexus-snapshots</id>      <username>admin</username>      <password>admin123</password>  </server></servers>

进入windows命令行，在工程所在目录下执行

mvn deploy

所部署的包就自动上传到了nexus安装目录下的/maven/nexus/sonatype-work/nexus/storage/releases/com/vclk/mkt/crawler/MarketingCrawler/0.3目录

nexus仓库中各目录介绍

项目中的各种jar包和项目快照等都放在/nexus/sonatype-work/nexus/storage/目录下，在这个目录下包括以下各种目录和存放相应文件。

/nexus/sonatype-work/nexus/storage/central - 用于放置maven从中央仓库中下载下来的项目pom.xml中配置到的相关jar包；

/nexus/sonatype-work/nexus/storage/thirdparty - 用于放置自己手动上传的第三方jar包；

/nexus/sonatype-work/nexus/storage/releases - 用于放置项目deploy后的发布版。
