搭建Maven的Nexus3私服

本文主要是介绍搭建Maven的Nexus3私服，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

搭建Maven的Nexus3私服

1、常见的Maven私服产品

1. Apache的Archiva
2. JFrog的Artifactory
3. Sonatype的Nexus（[ˈneksəs]）（当前最流行、使用最广泛）

2. windows java8安装和配置私服Nexus3

下载

下载地址：https://help.sonatype.com/repomanager3/product-information/download

最新版本地址：

https://sonatype-download.global.ssl.fastly.net/repository/downloads-prod-group/3/nexus-3.67.1-01-java8-win64.zip

安装

• 解压nexus-3.58.1-02-win64.zip，配置系统环境变量NEXUS_HOME。

λ echo %NEXUS_HOME%
D:\devtools\nexus-3.58.1-02-win64\nexus-3.58.1-02

并将%NEXUS_HOME%\bin加入Path。Nexus3自带了jre，可以按需替换成其他的版本。

• 修改端口号和ContextPath，配置文件路径%NEXUS_HOME%\etc\nexus-default.properties

## DO NOT EDIT - CUSTOMIZATIONS BELONG IN $data-dir/etc/nexus.properties
##
# Jetty section
# 端口号
application-port=8081
application-host=0.0.0.0
nexus-args=${jetty.etc}/jetty.xml,${jetty.etc}/jetty-http.xml,${jetty.etc}/jetty-requestlog.xml
# ContextPath
nexus-context-path=/# Nexus section
nexus-edition=nexus-pro-edition
nexus-features=\nexus-pro-featurenexus.hazelcast.discovery.isEnabled=true

• 修改JVM参数，配置文件路径%NEXUS_HOME%\etc\nexus.vmoptions 这个可以不改

-Xms2703m
-Xmx2703m
-XX:MaxDirectMemorySize=2703m
-XX:+UnlockDiagnosticVMOptions
-XX:+LogVMOutput
-XX:LogFile=../sonatype-work/nexus3/log/jvm.log
-XX:-OmitStackTraceInFastThrow

启动和安装nexus系统服务

这是我见过最傻的！！！

直接输入命令

nexus.exe/run

启动成功

登录http://localhost:8081/

λ nexus --help
Usage: nexus.exe /install | /uninstall | /stop | /start | /status | /run | /run-redirect

• nexus /run 控制台启动
• nexus /run-redirect 控制台启动可重定向标准输出和错误流到日志文件
• nexus /install 安装nexus系统服务
• nexus /uninstall 卸载nexus系统服务
• nexus /stop 停止nexus系统服务
• nexus /start 启动nexus系统服务

首次启动后会在%NEXUS_HOME%\sonatype-work\nexus3目录下生成admin.password文件，文件中内容就是admin用户的登陆密码。登陆进去之后会提示修改密码，修改完成之后会移除密码文件。

通过文件内容查看登录密码：

• 2.x的版本，初始账户和密码分别为admin和admin123
• 3.x的版本，初始账户是admin，密码在sonatype-work\nexus3\admin.password文件里

配置阿里云代理仓库

阿里云Maven仓库配置指南(仓库服务)

阿里云代理maven仓库地址：https://maven.aliyun.com/repository/central

创建仓库

选择maven2(proxy)

创建阿里云代理仓库

已经创建好的仓库

配置仓库组

选择maven-public

保存配置

修改%MAVEN_HOME%/conf/setting.xml

修改servers和``mirrors`节点配置：

<servers><server><id>maven-snapshots</id><username>登陆用户</username><password>密码</password></server><server><id>maven-releases</id><username>登陆用户</username><password>密码</password></server><server><id>maven-public</id><username>登陆用户</username><password>密码</password></server></servers><mirrors><mirror><id>maven-snapshots</id><mirrorOf>*</mirrorOf><url>http://localhost:10000/nexus/repository/maven-snapshots/</url><blocked>false</blocked></mirror><mirror><id>maven-releases</id><mirrorOf>*</mirrorOf><url>http://localhost:10000/nexus/repository/maven-releases/</url></mirror><mirror><id>maven-public</id><mirrorOf>*</mirrorOf><url>http://localhost:10000/nexus/repository/maven-public/</url></mirror> </mirrors>

保存文件，至此就全部配置好了。

发布构建

在项目的pom.xml中增加要发布的仓库地址，比如需要发布releases构建，配置如下：

    <distributionManagement><snapshotRepository><id>maven-snapshots</id><url>http://localhost:10000/nexus/repository/maven-snapshots/</url></snapshotRepository><repository><id>maven-releases</id><url>http://localhost:10000/nexus/repository/maven-releases/</url></repository></distributionManagement>

然后执行mvn deploy
